CVE-2025-21998

Description

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.
