medium Tenable Self-Hosted Container Security Plugin ID 475192

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: af_unix: Return immediately when
manage_oob() returns NULL for 0-length buffer. Fahad Alharbi reported that recv(0, MSG_PEEK) triggers
busy-wait in unix_stream_read_generic() if recv() is blocking and the last skb in the queue is MSG_OOB
skb. In such a situation, TCP returns 0 immediately regardless of blocking or non-blocking. Let's follow
the behaviour. (CVE-2026-98394)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.549.7 or later.
