high Tenable Cloud Security Plugin ID 467093

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 replacing
page cache folio fuse_try_move_folio() unlocks the request on entry but does not re-lock it on the success
path. This means fuse_chan_abort() can end the request and free the fuse_io_args (eg fuse_readpages_end())
while the subsequent copy chain logic after fuse_try_move_folio() accesses the fuse_io_args, leading to
use-after-free issues. Fix this by calling lock_request() before replace_page_cache_folio(). This ensures
the request is locked on the success path which will prevent the fuse_io_args from being freed while the
later copying logic runs, and also ensures that the ap->folios[i]->mapping is never null since
ap->folios[i] will always point to the newfolio after replace_page_cache_folio(). (CVE-2026-53388)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.36 or later.
