high Tenable Self-Hosted Container Security Plugin ID 474950

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: exec: do_close_on_exec() before taking
 exec_update_lock do_close_on_exec() currently happens while holding the exec_update_lock, which is used in
 a lot of places that access process state to synchronize access checks. I recently added another such use
 of exec_update_lock, causing a regression. do_close_on_exec() can block waiting for a reply from a
 filesystem. That means a hung filesystem can block codepaths that use exec_update_lock; and it also means
 that a FUSE filesystem which attempts to inspect the calling process can deadlock. To avoid such problems,
 move do_close_on_exec() before the exec_update_lock is taken, but after the FD table has been copied if
 necessary. I have looked through all the calls between the old and new position of the do_close_on_exec()
 call; there seems to be no file descriptor table access in between. (CVE-2026-98388)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
