An attacker who can successfully exploit this vulnerability can read or access sensitive data stored in the TPM.", "An out-of-bound read vulnerability was found in the TPM 2.0's Module Library, which allows the reading of 2-byte data after the end of the TPM command. This flaw allows an attacker to leak confidential data stored within the libtpms context." ],
