medium Tenable Self-Hosted Container Security Plugin ID 463992

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: wifi: rtw88: check for PCI upstream
 bridge existence pci_upstream_bridge() returns NULL if the device is on a root bus. If 8821CE is installed
 in the system with such a PCI topology, the probing routine will crash. This has probably been unnoticed
 as 8821CE is mostly supplied in laptops where there is a PCI-to-PCI bridge located upstream from the
 device. However the card might be installed on a system with different configuration. Check if the bridge
 does exist for the specific workaround to be applied. Found by Linux Verification Center
 (linuxtesting.org) with Svace static analysis tool. (CVE-2026-46092)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
