ASP Secure OS: Privilege Escalation via Buffer Overflow in TA
CVE-2022-23817 Published on August 13, 2024

Insufficient checking of memory buffer in AMD Secure Processor (ASP) Secure OS may allow an attacker with a malicious trusted application to read/write to the ASP Secure OS kernel virtual address space, potentially resulting in privilege escalation.

Weakness Types

Improper Input Validation

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

What is a Classic Buffer Overflow Vulnerability?

The program copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. A buffer overflow condition exists when a program attempts to put more data in a buffer than it can hold, or when a program attempts to put data in a memory area outside of the boundaries of a buffer. The simplest type of error, and the most common cause of buffer overflows, is the "classic" case in which the program copies the buffer without restricting how much is copied. Other variants exist, but the existence of a classic overflow strongly suggests that the programmer is not considering even the most basic of security protections.

CVE-2022-23817 has been classified to as a Classic Buffer Overflow vulnerability or weakness.
