medium Tenable Self-Hosted Container Security Plugin ID 471043

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: fwctl: Fix class init ordering to
 avoid NULL pointer dereference on device removal CXL is linked before fwctl in drivers/Makefile. Both use
 `module_init, so `cxl_pci_driver_init()` runs first. When `cxl_pci_probe()` calls `fwctl_register()` and
 then `device_add()`, fwctl_class is not yet registered because fwctl_init() hasn't run, causing
 `class_to_subsys()` to return NULL and skip knode_class initialization. On device removal,
 `class_to_subsys()` returns non-NULL, and `device_del()` calls `klist_del()` on the uninitialized knode,
 triggering a NULL pointer dereference. (CVE-2026-53042)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 19862.0.0 or later.
