1th percentile - higher than 1% of all known CVEs

Summary

A memory corruption vulnerability occurs when the non-secure loader rewrites page tables before secure memory initialization. This can corrupt memory structures used by security mechanisms.

Risk Assessment

It may lead to memory corruption and potential bypass of security mechanisms or system instability. In environments using secure boot, the risk is elevated.

Recommendation

Apply available vendor firmware/software updates that eliminate the race between the loader and secure memory initialization. If no fix is available, restrict access to the non-secure loader and monitor for abnormal system behavior.
