Can you explain this vulnerability to me?
This vulnerability involves improper input validation within the RAS TA Driver. It allows a local attacker to access memory outside the intended boundaries (out-of-bounds memory), which can lead to unexpected behavior.
Such improper validation means that the driver does not correctly check or restrict the input it receives, enabling an attacker with local access to exploit this flaw.
