The vulnerabilities, tracked as CVE-2023-1017 and CVE-2023-1018, provide pathways for an authenticated, local attacker to overwrite protected data in the TPM firmware and launch code execution attacks, according to an advisory from Carnegie Mellon’s CERT coordination center.

From the CERT alert:

“An authenticated, local attacker could send maliciously crafted commands to a vulnerable TPM allowing access to sensitive data. In some cases, the attacker can also overwrite protected data in the TPM firmware. This may lead to a crash or arbitrary code execution within the TPM. Because the attacker’s payload runs within the TPM, it may be undetectable by other components of the target device.”
