Published Apr 3, 2025

EPSS 0.14%
Description
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.
