Google: sys-kernel/lakitu-kernel-5_15, sys-kernel/lakitu-kernel-6_1: security update to 17800.436.32

medium Tenable Self-Hosted Container Security Plugin ID 453318

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 bpf_sk_select_reuseport()
 memory leak As pointed out in the original comment, lookup in sockmap can return a TCP ESTABLISHED socket.
 Such TCP socket may have had SO_ATTACH_REUSEPORT_EBPF set before it was ESTABLISHED. In other words, a
 non-NULL sk_reuseport_cb does not imply a non-refcounted socket. Drop sk's reference in both error paths.
