Synopsis

Moderate: kernel security, bug fix, and enhancement update



Description

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

Security Fix(es):

* kernel: RDMA/uverbs: Validate wqe_size before using it in ib_uverbs_post_send (CVE-2026-45856)

* kernel: KVM: SVM: Fix page overflow in sev_dbg_crypt() for ENCRYPT path (CVE-2026-63794)

* kernel: futex: Fix race on the initial mm->futex.phash.ref allocation (CVE-2026-80775)

Bug Fix(es) and Enhancement(s):

* Backport of protocol attribute to IP addresses (IFA_PROTO) [rhel-9.8.z] (JIRA:Rocky Linux-169936)

* try_charge_memcg() refactor in kernel 5.14.0-687.36.1 causes premature memcg OOM with GiB of clean page cache present [rhel-9.8.z] (JIRA:Rocky Linux-269060)
