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: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create() (CVE-2024-56602)
  • kernel: ip6_gre: Use cached t->net in ip6erspan_changelink() (CVE-2026-46120)
  • kernel: sched/psi: fix race between file release and pressure write (CVE-2026-52991)
  • kernel: mm/huge_memory: update file PMD counter before folio_put() (CVE-2026-53189)
  • kernel: scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd() (CVE-2026-63888)
  • kernel: scsi: target: iscsi: Bound iscsi_encode_text_output() appends to rsp_buf (CVE-2026-63887)
  • kernel: net/smc: reject CHID-0 ACCEPT that matches an empty ism_dev slot (CVE-2026-64048)
  • kernel: smb: client: mask server-provided mode to 07777 in modefromsid (CVE-2026-64379)
  • kernel: smb/client: handle overlapping allocated ranges in fallocate (CVE-2026-68388)

Bug Fix(es) and Enhancement(s):

  • sfc: TX queue stalls and NIC resets caused by GFP_ATOMIC allocation failures after AlmaLinux 8.10 kernel update (JIRA:AlmaLinux-219767)
