RHSA-2026:43307 - Important: kernel security, bug fix, and enhancement update

Synopsis

Important: kernel security, bug fix, and enhancement update

Type/Severity

Security Advisory: Important

Topic

An update for kernel is now available for Red Hat Enterprise Linux 9.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

• kernel: crypto: af_alg - zero initialize memory allocated via sock_kmalloc (CVE-2025-71113)

• kernel: scsi: core: Wake up the error handler when final completions race against each other (CVE-2026-23110)

• kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels (CVE-2026-46099)

• kernel: fanotify: fix false positive on permission events (CVE-2026-46150)

• kernel: drm: Set old handle to NULL before prime swap in change_handle (CVE-2026-46215)

• kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp (CVE-2026-53071)

Bug Fix(es) and Enhancement(s):

• [RHEL9] tools/lib/perf/Makefile: libperf includes appended after CFLAGS causes parallel build race, breaking kernel builds [rhel-9.8.z] (JIRA:RHEL-183980)

• [RHEL-9.8.z]: mlx5: include bug fixes (JIRA:RHEL-188121)

• dpll: fix NULL pointer dereference in dpll_msg_add_pin_ref_sync() [rhel-9.8.z] (JIRA:RHEL-212061)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
