Overview

CVE-2025-68729 is a known-severity vulnerability. It was published on December 24, 2025.

Technical description

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

wifi: ath12k: Fix MSDU buffer types handling in RX error path

Currently, packets received on the REO exception ring from

unassociated peers are of MSDU buffer type, while the driver expects

link descriptor type packets. These packets are not parsed further due

to a return check on packet type in ath12k_hal_desc_reo_parse_err(),

but the associated skb is not freed. This may lead to kernel

crashes and buffer leaks.

Hence to fix, update the RX error handler to explicitly drop

MSDU buffer type packets received on the REO exception ring.

This prevents further processing of invalid packets and ensures

stability in the RX error handling path.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1

How can CyberStrike help with CVE-2025-68729?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-68729 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
