This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.
Affected devices do not properly limit access through its Built-In-Self-Test (BIST) mode. This could allow an attacker with physical access to the serial interface to bypass authentication and get access to a root shell on the device.
