Summary
Important: kernel security, bug fix, and enhancement update
Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: calipso: Don't call calipso functions for AF_INET sk. (CVE-2025-38147)

  • kernel: ipv4: raw: reject IP_HDRINCL packets with ihl < 5 (CVE-2026-64114)

  • kernel: net/smc: reject CHID-0 ACCEPT that matches an empty ism_dev slot (CVE-2026-64048)

  • kernel: ALSA: hda/cs35l41: Fix firmware load work teardown (CVE-2026-64481)

  • kernel: fuse: re-lock request before returning from fuse_ref_folio() (CVE-2026-64266)

  • kernel: ipv4: fib: free fib_alias with kfree_rcu() on insert error path (CVE-2026-64572)

  • kernel: drm/amd/display: set new_stream to NULL after release (CVE-2026-68236)

  • kernel: ALSA: seq: close a re-opened queue timer in the destructor (CVE-2026-68202)

  • kernel: drm/dp/mst: fix buffer overflows in sideband chunk accumulation (CVE-2026-68278)

  • kernel: drm/amdgpu: fix lifetime issue of amdgpu_vm_get_task_info_pasid() (CVE-2026-68245)

  • kernel: ovl: check access to copy_file_range source with src mounter creds (CVE-2026-68448)

  • kernel: xfs: bounds-check buffer log item's dirty bitmap (CVE-2026-80536)

  • kernel: inet: frags: strip GSO state from fragments before reassembly (CVE-2026-80590)

  • kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound (CVE-2026-80887)

  • kernel: perf: Fix use-after-free when perf mmap() revival races with the last munmap() (CVE-2026-89791)

  • kernel: drm/amdkfd: Add TLB flush after MES queue eviction/suspension (CVE-2026-89811)

  • kernel: perf: Fix addr_filter_ranges lifetime (CVE-2026-93817)

  • kernel: drm/amdgpu: Bound GPIO I2C table entry count from VBIOS (CVE-2026-97493)

Bug Fix(es) and Enhancement(s):

  • Backport request: bonding: only set speed/duplex to unknown, if getting speed failed [rhel-10.2.z] (JIRA:Rocky Linux-179066)

  • RTLA segfaults on freed memory access on double SIGINT [rhel-10.2.z] (JIRA:Rocky Linux-193031)
