Overview

CVE-2024-53191 is a high-severity vulnerability. It was published on December 27, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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: ath12k: fix warning when unbinding

If there is an error during some initialization related to firmware,

the buffers dp->tx_ring[i].tx_status are released.

However this is released again when the device is unbinded (ath12k_pci),

and we get:

WARNING: CPU: 0 PID: 2098 at mm/slub.c:4689 free_large_kmalloc+0x4d/0x80

Call Trace:

free_large_kmalloc

ath12k_dp_free

ath12k_core_deinit

ath12k_pci_remove

...

The issue is always reproducible from a VM because the MSI addressing

initialization is failing.

In order to fix the issue, just set the buffers to NULL after releasing in

order to avoid the double free.

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.
