Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker with physical access and control of a Uapp that runs under the bootloader to reveal the contents of the ASP (AMD Secure Processor) bootloader accessible memory to a serial port, resulting in a potential loss of integrity. Zafiyet ile ilgili Genel…
A malicious or compromised UApp or ABL can send a malformed system call to the bootloader, which may result in an out-of-bounds memory access that may potentially lead to an attacker leaking sensitive information or achieving code execution.
