medium Tenable Self-Hosted Container Security Plugin ID 475512

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: eventfs: Initialize ei->children and
ei->list in init_ei() eventfs_create_dir() allocates the eventfs_inode and initializes it with init_ei().
But this does not initialize the eventfs_inode list_heads. If the eventfs_create_dir() fails due to memory
pressure, it will call free_ei() before it initialized the lists, and that checks to make sure the
eventfs_inode has no children. But because the list wasn't initialized, it will give a false warning. Fix
it by moving the list initialization into init_ei(). [ Rewrote change log ] (CVE-2026-89618)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
