Recommendation: Monitor — no exploitation signal at the moment.
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.
