Overview

CVE-2025-38116 is a high-severity vulnerability. It was published on July 3, 2025 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 uaf in ath12k_core_init()

When the execution of ath12k_core_hw_group_assign() or

ath12k_core_hw_group_create() fails, the registered notifier chain is not

unregistered properly. Its memory is freed after rmmod, which may trigger

to a use-after-free (UAF) issue if there is a subsequent access to this

notifier chain.

Fixes the issue by calling ath12k_core_panic_notifier_unregister() in

failure cases.
