OpenSSH is a set of computer programs providing encrypted communication sessions over a computer network using the SSH protocol.

In OpenSSH, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit.

Affected Versions:
OpenSSH before version 9.6

QID Detection Logic:
This unauthenticated detection works by reviewing the version of the OpenSSH service.

Successful exploitation allows OS command injection and row hammer attacks for authentication bypass.

CVSS V3 rated as High - 7 severity.
