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: tcp: fix potential race in tcp_v6_syn_recv_sock() (CVE-2026-43198)
  • kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table() (CVE-2026-43450)
  • kernel: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL (CVE-2026-46227)
  • kernel: drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs() (CVE-2026-46209)
  • kernel: procfs: fix missing RCU protection when reading real_parent in do_task_stat() (CVE-2026-46259)
  • kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources (CVE-2025-10263)

Bug Fix(es) and Enhancement(s):

  • kernel panic at trailing_symlink while the task wdavdaemon runs even after 4c4f7c19b3c7 (JIRA:AlmaLinux-152759)
