Overview

CVE-2023-52829 is a high-severity vulnerability. It was published on May 21, 2024 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

wifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps()

reg_cap.phy_id is extracted from WMI event and could be an unexpected value

in case some errors happen. As a result out-of-bound write may occur to

soc->hal_reg_cap. Fix it by validating reg_cap.phy_id before using it.

This is found during code review.

Compile tested only.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
