- Summary
- ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41getacpimutestate()
Return value of a function acpievaluatedsm() is dereferenced without checking for NULL, but it is usually checked for this function.
acpievaluatedsm() may return NULL, when acpievaluateobject() returns acpistatus other than ACPISUCCESS, so add a check to prevent the crach.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
