Overview

CVE-2022-50418 is a medium-severity vulnerability. It was published on September 18, 2025 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: ath11k: mhi: fix potential memory leak in ath11k_mhi_register()

mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets

some error, mhi_ctrl should be freed with mhi_free_controller(). But

when ath11k_mhi_read_addr_from_dt() fails, the function returns without

calling mhi_free_controller(), which will lead to a memory leak.

We can fix it by calling mhi_free_controller() when

ath11k_mhi_read_addr_from_dt() fails.

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.
