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, sockmap: Fix sk_redir use-after-
 free in send verdict sk_psock_msg_verdict() takes a socket reference for psock->sk_redir.
 tcp_bpf_send_verdict() copies that pointer while holding the source socket lock, but does not take a
 reference for the local copy before dropping the lock around tcp_bpf_sendmsg_redir(). When apply_bytes
 keeps the cached verdict active, another sendmsg() on the same source socket can consume the remaining
 bytes and release the cached reference while the first thread still holds only the raw local pointer: CPU
 0 CPU 1 sk_redir = psock->sk_redir apply_bytes remains nonzero release_sock(sk) lock_sock(sk) apply_bytes
 reaches zero psock->sk_redir = NULL release_sock(sk) tcp_bpf_sendmsg_redir(sk_redir) sock_put(sk_redir)
 tcp_bpf_sendmsg_redir(sk_redir) The final sock_put() can free sk_redir before CPU 0 dereferences it. KASAN

 independent of cached-verdict ownership. (CVE-2026-74589)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
