high Tenable Cloud Security Plugin ID 475299

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: xfs: fix the rtrmap and rtrefcount
_maxlevels_ondisk functions The _maxlevels_ondisk functions are used to compute the size of in-memory
btree cursors for each btree type. Unfortunately, LOLLM noticed that the rtrmap and rtrefcount versions of
these functions forget to account for the inode root, which means that we could access beyond the end of
the cursor given a sufficiently large btree. Fix this. (CVE-2026-97548)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19999.44.106 or later.
