Overview

CVE-2024-53189 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: nl80211: fix bounds checker error in nl80211_parse_sched_scan

The channels array in the cfg80211_scan_request has a __counted_by

attribute attached to it, which points to the n_channels variable. This

attribute is used in bounds checking, and if it is not set before the

array is filled, then the bounds sanitizer will issue a warning or a

kernel panic if CONFIG_UBSAN_TRAP is set.

This patch sets the size of allocated memory as the initial value for

n_channels. It is updated with the actual number of added elements after

the array is filled.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
