Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: bpf, cgroup: Fix storage null-ptr-
 deref after replacing prog Syzkaller reported a storage null-ptr-deref issue after replacing prog. This
 occurs in the following scenario: 1. prog A, an empty prog, is attached to a cgrp. 2. prog B uses
 BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE and calls the bpf_get_local_storage helper. 3. link_update is called to
 replace prog A with prog B. The reason is that __cgroup_bpf_replace fails to alloc and assign the required
 cgrp storage for the incoming replacement prog. Consequently, the new prog inherits an uninit storage,
 leading to null-ptr-deref panic when kick the new prog. Fix this by rejecting a link update if new_prog's
 cgroup storage is incompatible with link->prog. (CVE-2026-90250)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
