medium Tenable Self-Hosted Container Security Plugin ID 466150

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 reference count leak in
bpf_prog_test_run_xdp() syzbot is reporting unregister_netdevice: waiting for sit0 to become free. Usage
count = 2 problem. A debug printk() patch found that a refcount is obtained at xdp_convert_md_to_buff()
from bpf_prog_test_run_xdp(). According to commit ec94670fcb3b ("bpf: Support specifying ingress via
xdp_md context in BPF_PROG_TEST_RUN"), the refcount obtained by xdp_convert_md_to_buff() will be released
by xdp_convert_buff_to_md(). Therefore, we can consider that the error handling path introduced by commit
1c1949982524 ("bpf: introduce frags support to bpf_prog_test_run_xdp()") forgot to call
xdp_convert_buff_to_md(). (CVE-2026-22994)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.439.120 or later.
