New Features and Enhancements

KDE Gear 26.04.1: Akonadi fixes a crash in EntityTreeView when selecting multiple items, and KOrganizer resolves black squares in the todo view and re-enables icons in monthview. Dolphin refines the selection panel and search popup behavior. Kate restores middle-click closing of tabs when the close button is disabled, Konsole prevents QTabBar from closing tabs on stray middle clicks, and Okular hardens fax handling against malformed .g3 inputs. Umbrello gets six bug fixes including diagram-load and Qt6 configuration crashes, and Itinerary adds new Condor PKPass and monbus.es ticket extractors.

KDE Frameworks 6.26.0: KIO adds the Startpage search provider, expands KFilePlacesModel with kdeconnect device support, gains MIME-type detection from text content in the paste flow, and exposes the current folder in the file widget placeholder. KCoreAddons introduces KAboutRelease for listing application release notes, parses AppStream release notes, and switches to libmount for filesystem-type detection where available. KImageFormats corrects EXR loading from Photoshop 2026 saves, plugs JXR memory leaks, and improves EXIF handling. KHolidays introduces HolidayCategories and fixes Philippines Easter holidays.

Plasma 6.6.5: KWin gains numerous DRM backend fixes including correctly updating outputs only on changed GPUs, preserving custom output modes across reboots, setting full color range for RGB planes on NVIDIA, and avoiding multi-GPU copies with unsupported formats. Input handling is hardened by mapping devices to device outputs (not logical ones), processing key repeat before the accessibility monitor, and cleaning up keyboard grabs on shutdown. KScreen hides the DDC/CI option when HDR is enabled and prevents off-by-one gaps when creating replicas. Discover corrects text color inversion in ProgressView, and Plasma Workspace fixes klipper clipboard updates, lockscreen timezone init races on multi-screen, and broken text legibility with the Air and Breeze Light themes. Spectacle keeps the application alive briefly after copying screenshots and fixes magnifier activation during hover events. PowerDevil addresses screen brightness getting stuck at 30 percent after a restart.

GNOME 50.1 and 50.2: These point releases bring stability and usability fixes across the GNOME desktop. GDM 50.1 fixes a failure to properly terminate conflicting graphical sessions started outside of GDM (such as ThinLinc or TigerVNC) by querying logind directly, and resolves Plymouth hanging indefinitely on headless systems or those without monitors. A bug incorrectly setting XDG_SESSION_TYPE=wayland on X11 sessions was corrected, along with XDG_DATA_DIRS construction that could prevent GNOME Shell from finding its files. GNOME Shell 50.2 fixes extending screenshot area selection to monitor edges, adds rate control to VA-API H.264 screencast pipelines, and restores the “Install Updates” checkbox in the power-off/restart dialog. Autorun notifications for USB drives, spinner resets during overview search, and wiggle feedback on non-password auth failures are all corrected, and the audio input icon now only appears when actually recording. GNOME Control Center 50.2 fixes the “Show Content” notification setting, relaxes app-id validation for Global Shortcuts, and improves mobile-width label fitting in Device Security and Wellbeing panels. GNOME Session 50.1 fixes a double-free bug. For Tumbleweed users, these updates improve login reliability, screencast quality, and overall GNOME desktop polish.

KDE Network File Sharing 26.04.0: This update refactors the file properties plugin initialization and now automatically enables and starts the Samba service if needed when sharing folders. Service aliases are handled correctly, the user list in combo boxes is clipped with scrolling disabled for better usability, and a regression in smbd path lookup was fixed.

AppArmor 5.0.0: This major version bump from the 4.1 series is a significant milestone for the mandatory access control framework. The release modernizes the parser and userspace utilities, adopts a new ABI abi/5.0, and introduces broader profile updates. Profiles for samba, dovecot, postfix, wpa_supplicant, and syslog-ng are refined to better handle modern filesystem layouts. The full upstream changelog is available at the AppArmor 5.0 release notes wiki.

GnuPG 2.5.20: This update implements GCM encryption in gpgsm (decryption was already supported in earlier versions), adds the --attribute option and SETATTR server command for including arbitrary signed or unsigned attributes in signatures, and introduces a new system attribute _signingCertificateV2. A possible double free in the CMS parser is fixed, along with a buffer overflow in scdaemon when handling SC-HSM cards with RSA keys larger than 2 kilobits. Several agent and keyboxd fixes correct loopback pinentry caching and PUT_SECRET input handling.

libusb 1.0.30: This update introduces new APIs libusb_get_device_string() and libusb_get_session_data() for accessing device strings without opening the device and retrieving OS-specific handles. Device removal races on non-hotplug builds are fixed and descriptor parsing memory safety is improved.

poppler 26.05.0: This jump from 26.02.0 rolls up three upstream releases. The release improves reconstruction of damaged files, fixes crashes in malformed documents, and removes the PSOutputDev “pipe as filename” feature for security reasons. pdftotext gains a -remove-hyphens option and no longer aborts on empty strings. The qt5/qt6 search APIs receive a fix for inverted continuation rectangles, and the GPG signature backend correctly marks qualified keys.

gpg2 and libksba 1.8.0: The S/MIME-related X.509 and CMS support library jumps from 1.6.8 to 1.8.0. New functions include ksba_cms_add_attribute and ksba_cms_get_attribute, support for building AuthEnvelopedData, and corrections to silent truncation of 64-bit length fields and overflow guard conditions in _ksba_ber_read_tl.

open-vm-tools 13.1.0: This major version bump introduces support for GTK4 alongside continued GTK3 compatibility. The configure script accepts options to restrict the build to either toolkit; otherwise it picks the latest available. Several upstream GitHub issues are resolved as documented in the 13.1.0 Release Notes.

fwupd 2.1.3: This update for the firmware update daemon continues to add features and hardware coverage. New capabilities include Redfish bearer token authentication, support for several XMC SPI chips, parsing of JCat files without libjcat, native CBOR parsing (dropping libcbor2 as a dependency), and an HSI check for AMD SB-7033 (a.k.a. EntrySign). The earlier 2.1.2 release also added native EFI authenticated variable loading with ContentInfo headers and decompression-ratio limits to prevent ZIP-bomb-style emulation parsing. New hardware support spans the SHIFT6mq, SHIFTphone 8, Google Moonstone, Lenovo USB-4 dock, HP 400/405 Mouse, Parade USB hubs with GPIO control, Pixart PLP239 devices, Raydium TP devices, Sunplus cameras, and the LX Semicon SW42101 touch controller.

python-cryptography 48.0.0: A major version bump that drops Python 3.8 support and changes X.509 CRL parsing so that a mismatched inner TBSCertList.signature and outer signatureAlgorithm raises a ValueError. ML-KEM and ML-DSA are now supported when building against OpenSSL 3.5.0 or later (in addition to AWS-LC and BoringSSL), bringing post-quantum algorithms to upstream wheel users.

Key Package Updates

Linux Kernel 7.0.9: The kernel progressed through 7.0.5, 7.0.6, 7.0.7 and 7.0.9 during the month, accumulating a substantial pile of security and stability fixes. The 7.0.5 release fixed a buffer overflow in vrealloc_node_align() along with a deadlock in mmap_prepare error handling when holding rmap. The crypto subsystem received extensive fixes including memory leaks in atmel-aes, ccree, and nx842, a use-after-free in atmel-sha204a removal, and short digest rejection in authencesn. netfilter rejects zero shifts in nft_bitwise, and IPsec (xfrm) avoids in-place decryption on shared skb fragments. NTFS3 receives integer overflow and buffer boundary checks in run_unpack(), and EROFS fixes an unsigned underflow in LZ4 overlap handling. The 7.0.6 follow-up added an rxrpc fix for DATA/RESPONSE packets when paged frags are present and an ALSA fasync state-check serialization. The 7.0.7 release brought multiple CVE fixes detailed below, scsi target configfs bounds tightening in snprintf(), ipmi event/receive message limits, KVM x86 shadow-paging use-after-free protection, smbdirect MR registration fixes for coalesced SG lists, and many wifi mt76 fixes for mt7921/mt7925. The 7.0.9 jump adds HID fixes (PlayStation num_touch_reports clamp, appletb-kbd UAF on inactivity-timer cleanup, pidff integer overflow), drm/gpusvm correctness fixes, and many spi controller deregistration fixes.

curl 8.20.0: This release addresses half a dozen security vulnerabilities. RTMP support is dropped entirely and SMB support is now opt-in. A new thread pool and queue system was added for async resolution, and HTTPS DNS record resolution is made more reliable. Credential handling is hardened across redirects, with digest nonces cleared on cross-origin redirects and proxy credentials cleared on port or scheme changes. The alt-svc and HSTS lists are now capped (at 5,000 entries) and expired entries are skipped when reading from file. HTTP/2 now prevents secure schemes being pushed over insecure connections, and MIME processing limits nesting to 40 levels.

GnuTLS 3.8.13: This major security release addresses more than a dozen vulnerabilities. Three high-severity DTLS reassembly issues are fixed. Medium-severity fixes address a use-after-free in gnutls_pkcs11_token_set_pin(), an overread in RSA key exchange with PKCS#11 keys, CN fallback suppression issues with URI/SRV SANs, and intersecting empty name constraints. Lower-severity fixes cover a multi-entry OCSP response revocation bypass, a timing side-channel in PKCS#7 padding removal, and an off-by-one in PKCS#12 bag bounds checking. HPKE (Hybrid Public Key Encryption, RFC 9180) is available as a technology preview, ML-DSA public key derivation from expanded private keys (RFC 9881) is supported, and building with Nettle 4.0 is now possible. TLS 1.3 client certificate selection is fixed for servers advertising only rsa_pss_rsae_* algorithms, and kTLS ChaCha20-Poly1305 IV handling is corrected for TLS 1.2.

GLib 2.88.1: This update fixes a miscompilation with GCC 16 caused by incorrect function attribute usage. A flag confusion security issue in GRegex when using G_REGEX_RAW is resolved, which could result in unbounded out-of-bounds heap reads off the start of a regex input string. Various minor security issues are also addressed, typically involving small out-of-bounds reads or scenarios relying on discouraged P2P D-Bus configurations.

SQLite 3.53.1: The recovery extension is hardened against SQL injections from the sqlite_schema table of databases being recovered. A crash in sqlite3_deserialize() when overwriting a database with an open transaction is fixed (a bug dating back to version 3.23.0). A single-byte out-of-bounds read in the session module when concatenating patchsets is corrected. The EXISTS-to-JOIN optimization receives fixes for OR-optimization early-exit logic and OFFSET clause handling. A printf() optimization regression causing sqlite3_snprintf() to incorrectly truncate floating-point conversions is resolved, and sqlite3_str_free() no longer crashes when called on objects returned after an out-of-memory condition.

Mesa 26.1.0 to 26.1.1: Version 26.1.1 fixes RADV sample shading with required sample-shaded inputs, VRS with mipmaps on GFX10.3, acceleration structure copies with DAC, and enables a VM map update workaround for Forza Horizon 6. ANV (Intel) adds a SIMD32 requirement heuristic for Dragon Dogma 2, fixes usage flags not propagated to ISL for explicit layouts, bumps the max compute workgroup count, and corrects timebase scale precision loss across 2^32 ticks. The Vulkan 1.4 API is now implemented, with support varying by driver with version 26.1.0. Experimental support for Intel Nova Lake P hardware is introduced. Zink now supports OpenGL ES 2.0 on PowerVR GPUs, expanding its reach to embedded hardware. New Vulkan and OpenGL extensions are supported across drivers including VK_EXT_present_timing, GL_NV_timeline_semaphore (RadeonSI), VK_QCOM_image_processing (Turnip), VK_KHR_present_id, and VK_KHR_present_wait. Rusticl (OpenCL) now requires a static C++ standard library. The update delivers broader Vulkan support, improved virtualization performance, and expanded hardware compatibility.

GStreamer 1.28.3: A bugfix release with security fixes across the framework. Highlights include applemedia vtdec stability, MoltenVK integration and planar video format handling fixes, an audioresample regression fix on armv7hf, bpmdetect corrections for stereo and multi-channel modes, and webrtcsink support for the imx8mp vpuenc_hevc H.265 encoder. Codec parsers receive multiple hardening fixes including a stack buffer overflow in the H.265 buffering period SEI parser, bounds checks in MPEG-TS PES header parsing, and a heap buffer overflow in MXF AES3 audio descriptor write_tags. The mxf and mpegtsdemux plugins receive numerous additional bounds and overflow fixes, and pngparse gets a use-after-free fix. Several memory leaks across decodebin2, subparse, samiparse, baseparse, and others are also addressed.

expat 2.8.1: This update jumps from 2.7.5 and addresses two security issues. A quadratic-runtime attack via attribute name collision checks is corrected, and the SipHash-based hash flooding protection now uses the full 16 bytes of salt instead of 4 to 8. The existing XML_SetHashSalt API is deprecated and a new XML_SetHashSalt16Bytes is introduced for callers that want to provide their own high-quality entropy.

rsync 3.4.3: A security-focused release fixing six CVEs in the file-synchronization tool. Three of the six (CVE-2026-29518, CVE-2026-43617, CVE-2026-43619) require non-default daemon configurations, two (CVE-2026-43618, CVE-2026-43620) are reachable from normal pulls or normal authenticated daemon connections, and the sixth (CVE-2026-45232) requires RSYNC_PROXY to be set with a pathological proxy response. Detailed CVE notes appear in the security section below. The release also adds defence-in-depth hardening on adjacent paths and fixes a regression introduced by the 3.4.0 secure_relative_open().

PostgreSQL 18.4: This point release of the database addresses 10 CVEs covering schema privilege checks, integer overflows in memory allocation calculations, time-zone name handling, path traversal in pg_basebackup and pg_rewind, subscription-name quoting in pg_createsubscriber, marking PQfn() as unsafe, timing-safe string comparisons in authentication, recursion limits in startup packet processing, MCV statistics validation, SQL injection protection in contrib/spi, and quoting of object names in logical replication origin checks. See the official 18.4 release announcement for full notes.

dnsmasq 2.92rel2: A security-focused point release fixing six CVEs in the DNS and DHCP server. Vulnerabilities include cache poisoning that could enable DoS or attacker redirection, DNSSEC validation flaws, a heap out-of-bounds read in DNSSEC validation, a heap out-of-bounds write in DHCPv6 handling, an information disclosure flaw allowing source-check bypass, and a buffer overflow in extract_addresses().

ImageMagick 7.1.2.23 and 7.1.2.24: The 7.1.2.24 version strengthens input validation by rejecting MTV, TGA, Cineon, and Farbfeld image files with zero columns or rows, preventing potential crashes or undefined behavior from malformed files. A new profile fuzzer is added for raw EXIF, XMP, IPTC, and ICC parsing to improve robustness. The 7.1.2.23 version rolls up many GitHub security advisories from upstream and applies an integer overflow fix tracked as CVE-2026-31853.

OpenEXR 3.4.11: A double update from 3.4.9 through 3.4.10 to 3.4.11 closes several additional CVEs in the EXR image format library. Fixes address a shift exponent overflow in readVariableLengthInteger(), an out-of-bounds read in IDManifest::init() during prefix expansion, an integer overflow in ImageChannel::resize, a signed integer overflow in ht_undo_impl() in the HTJ2K decoder, and two missed variants of the earlier DWA-decoder pointer arithmetic overflow.

ncurses 6.6.20260516: Two snapshot patches bring loop limit corrections in lib_twait.c, magic-cookie initialization deferral, terminal database refinements for kitty, contour, screen4/screen5, xterm-utf8, and warp, and a recur_wgetnstr() buffer limit correction.

hplip 3.26.4: A new release of the HP Linux Imaging and Printing project adds support for a broad range of new printers including the HP LaserJet Pro MFP 3106sdw/3105sdw, OfficeJet Pro 9730/9720/8130/8120 series, Envy 6500 series, and several DeskJet Ink Advantage models.

Vulkan SDK 1.4.350: Both vulkan-loader and vulkan-tools jump from 1.4.341 to 1.4.350. vulkaninfo now enables the device groups extension and checks extensions before querying properties, and a wrong extension being used for GGP is corrected.

Conclusion

May 2026 was a steady month for openSUSE Tumbleweed with point releases landing across all three major KDE stacks (KDE Gear 26.04.1, Frameworks 6.26.0, and Plasma 6.6.5). Mesa made the leap to 26.1 with the Vulkan 1.4 API, and AppArmor shipped its first 5.0 release. Sysadmins received headline updates across Apache HTTP Server 2.4.67, PostgreSQL 18.4, rsync 3.4.3, dnsmasq 2.92rel2, GnuPG 2.5.20, and expat 2.8.1 — almost all driven by CVE fixes. The Linux kernel progressed from 7.0.5 to 7.0.9 with broad subsystem hardening, and security was the dominant theme across PHP, OpenEXR, jq, ImageMagick, python-cryptography, python-urllib3, and a long tail of Perl networking modules.
