| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A use-after-free (UAF) issue was found in the Linux kernel, specifically in the
ath12k core init() function. This issue occurs when the execution of ath12k core hw group assign() or ath12k core hw group create() fails, and the registered notifier chain is not unregistered properly. The memory is freed after rmmod, which may trigger a UAF issue if there is a subsequent access to this notifier chain. The issue is fixed by calling ath12k core panic notifier unregister() in failure cases.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
