high Tenable Cloud Security Plugin ID 469306

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: re-lock request before returning
 from fuse_ref_folio() fuse_ref_folio() unlocks the request but does not re-lock it before returning.
 fuse_chan_abort() can end the request and the async end callback (eg fuse_writepage_free()) can free the
 args while the subsequent copy chain logic after fuse_ref_folio() accesses them, leading to use-after-free
 issues. Fix this by locking the request in fuse_ref_folio() before returning. (CVE-2026-64266)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.82 or later.
