CVSSv4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a null pointer dereference in the mt8365_afe_suspend() function of the MediaTek MT8365 AFE PCM driver when handling a suspend operation after register backup buffer allocation fails. A local user can trigger a suspend operation when register backup buffer allocation fails to cause a denial of service.

The runtime-suspend state may be updated even when the suspend operation fails.
