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: Fix out-of-bounds read of
 sk_protocol in bpf_sock_destroy() sk_protocol lives in struct sock, not in struct sock_common. A timewait
 or request sock handed to bpf_sock_destroy() by the tcp iterator is neither, so reading sk->sk_protocol
 runs past the object: ================================================================== BUG: KASAN: slab-

 how to deal with TIME_WAIT and NEW_SYN_RECV socks. Also fix the comment, it never matched the code.
 (CVE-2026-98384)
