medium Tenable Cloud Security Plugin ID 470489

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: fuse: abort on fatal signal during
sync init When sync init is used and the server exits for some reason (error, crash) while processing
FUSE_INIT, the filesystem creation will hang. The reason is that while all other threads will exit, the
mounting thread (or process) will keep the device fd open, which will prevent an abort from happening.
This is a regression from the async mount case, where the mount was done first, and the FUSE_INIT
processing afterwards, in which case there's no such recursive syscall keeping the fd open.
(CVE-2026-31713)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19804.0.0 or later.
