medium Tenable Self-Hosted Container Security Plugin ID 475567

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: pnfs/blocklayout: Fix device leaks on
parse failure bl_parse_concat() and bl_parse_stripe() allocate a child device array and then parse each
child in turn. If parsing a child fails, the failed child is not counted in nr_children and the parent may
be left with a children array that bl_free_device() will not release when nr_children is zero. Release the
failed child and the already parsed children before returning the error. Also make bl_free_device()
release the child array whenever the children pointer is set, so that partially initialised concat or
stripe devices are cleaned up correctly. bl_parse_scsi() can also fail after assigning d->bdev_file and
dropping the file reference. Clear the pointer after fput() so that an outer cleanup path does not put it
again. (CVE-2026-90150)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20198.0.0 or later.
