In the Linux kernel, the following vulnerability has been resolved:

arm64: acpi: Fix possible memory leak of ffh_ctxt

Allocated 'ffh_ctxt' memory leak is possible if the SMCCC version and conduit checks fail and -EOPNOTSUPP is returned without freeing the allocated memory.

Fix the same by moving the allocation after the SMCCC version and conduit checks.
