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: block: zero non-PI portion of auto integrity buffer (CVE-2026-23007)
  • kernel: af_unix: Drop all SCM attributes for SOCKMAP (CVE-2026-53005)
  • kernel: mac802154: llsec: add skb_cow_data() before in-place crypto (CVE-2026-63831)
  • kernel: blk-cgroup: fix UAF in __blkcg_rstat_flush() (CVE-2026-63802)
  • kernel: block: don't overwrite bip_vcnt in bio_integrity_copy_user() (CVE-2026-64053)
  • kernel: smb: client: fix double-free in SMB2_flush() replay (CVE-2026-64383)
  • kernel: nvmet-tcp: check INIT_FAILED before nvmet_req_uninit in digest error path (CVE-2026-64534)
  • kernel: sctp: don't free the ASCONF's own transport in DEL-IP processing (CVE-2026-64564)
  • kernel: ALSA: timer: drain a slave's callback before its master detaches it (CVE-2026-68201)
  • kernel: ASoC: SOF: ipc3-control: Validate size in snd_sof_update_control (CVE-2026-72261)
  • kernel: xfrm: ah6: validate routing header segments_left (CVE-2026-80844)
  • kernel: net: tun: bound receive headroom (CVE-2026-81000)
  • kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read (CVE-2026-89846)

Bug Fix(es) and Enhancement(s):

  • sctp: prevent peer transport count overflow [almalinux-9.8.z] (JIRA:AlmaLinux-216251)
  • netfilter: nftables CVE and memory safety backports for 9.8 (JIRA:AlmaLinux-236634)
