medium Tenable Self-Hosted Container Security Plugin ID 470113

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: btrfs: fix NULL dereference on root
when tracing inode eviction When evicting an inode the first thing we do is to setup tracing for it, which
implies fetching the root's id. But in btrfs_evict_inode() the root might be NULL, as implied in the next
check that we do in btrfs_evict_inode(). Hence, we either should set the ->root_objectid to 0 in case the
root is NULL, or we move tracing setup after checking that the root is not NULL. Setting the rootid to 0
at least gives us the possibility to trace this call even in the case when the root is NULL, so that's the
solution taken here. (CVE-2025-71184)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19738.0.0 or later.
