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: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item (CVE-2025-68211)

  • kernel: ip6_tunnel: use skb_vlan_inet_prepare() in __ip6_tnl_rcv() (CVE-2026-23003)

  • kernel: netfilter: nft_set_pipapo_avx2: don't return non-matching entry on expiry (CVE-2026-43114)

  • kernel: sctp: purge outqueue on stale COOKIE-ECHO handling (CVE-2026-52924)

  • kernel: netfilter: xt_policy: fix strict mode inbound policy matching (CVE-2026-52920)

  • kernel: zram: fix use-after-free in zram_bvec_write_partial() (CVE-2026-53185)

  • kernel: netfilter: require Ethernet MAC header before using eth_hdr() (CVE-2026-53131)

  • kernel: netfilter: conntrack_irc: fix possible out-of-bounds read (CVE-2026-53268)

  • kernel: i2c: stub: Reject I2C block transfers with invalid length (CVE-2026-64191)

  • kernel: netfilter: ipset: fix race between dump and ip_set_list resize (CVE-2026-64189)

  • kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count (CVE-2026-64277)

  • kernel: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count (CVE-2026-64276)

  • kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer (CVE-2026-74581)

Bug Fix(es) and Enhancement(s):

  • [Rocky Linux-9.8.z] Intel CWF: CPU is unable to obtain cstate1 on idle system (JIRA:Rocky Linux-166118)

  • ss core dumped when there is an SCTP session [rhel-9.8.z] (JIRA:Rocky Linux-212398)

  • [IBM 9.9 FEAT] zcrypt driver overwrite function - kernel part [rhel-9.8.z] (JIRA:Rocky Linux-245333)
