Vulnerability Title
wifi: ath12k: fix uaf in ath12k_core_init()
Source: CVE Program / CVE List V5
Vulnerability 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.
