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: virtiofs: fix UAF on submount umount
iput() called from fuse_release_end() can Oops if the super block has already been destroyed. Normally
this is prevented by waiting for num_waiting to go down to zero before commencing with super block
shutdown. This only works, however, for the last submount instance, as the wait counter is per connection,
not per superblock. Revert to using synchronous release requests for the auto_submounts case, which is
virtiofs only at this time. (CVE-2026-53381)

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.675.28 or later.
