Synopsis

Important: kernel security update

Description

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

Security Fix(es):

* kernel: Linux kernel: Use-after-free in traffic control (act_ct) may lead to denial of service or privilege escalation (CVE-2026-23270)

* kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache (CVE-2026-31402)

* kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service (CVE-2026-31419)

* kernel: crypto: algif_aead - Revert to operating out-of-place (CVE-2026-31431)

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.
