- Details
-
In the Linux kernel, the following vulnerability has been resolved:
firmware: qcom: uefisecapp: fix efivars registration race
Since the conversion to using the TZ allocator, the efivars service is registered before the memory pool has been allocated, something which can lead to a NULL-pointer dereference in case of a racing EFI variable access.
Make sure that all resources have been set up before registering the efivars.
