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: xfrm: espintcp: do not reuse an in-progress partial send (CVE-2026-52935)
  • kernel: USB: serial: io_ti: fix heap overflow in get_manuf_info() (CVE-2026-53196)
  • kernel: sctp: keep chunk->transport in step with the list it is queued on (CVE-2026-74588)
  • kernel: sctp: validate cookie AUTH state before use (CVE-2026-74752)
  • kernel: smb: client: reject a tree connect response whose byte count is too small (CVE-2026-89631)
  • kernel: sctp: stop processing a packet once its association is deleted (CVE-2026-89479)
  • kernel: perf: Fix addr_filter_ranges lifetime (CVE-2026-93817)
  • kernel: netfilter: nfnetlink_log: wait for rcu grace period before freeing pernet state (CVE-2026-93288)
  • kernel: kernel: strparser: use-after-free via msg_timer_work rearm after strp_done() cancellation ()
  • kernel: netfilter: flowtable: hold reference on ct until flow is released (CVE-2026-98320)

Bug Fix(es) and Enhancement(s):

  • gfs2 filesystem withdrawal rework [AlmaLinux-8] (JIRA:AlmaLinux-129363)
  • Batch: z-stream xfrm - almalinux-8.10.z (NST-Core-26W38) (JIRA:AlmaLinux-256684)
