Upstream information
Description
OpenSSH through 9.6, 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. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges.SUSE information

Note from the SUSE Security Team
Our analysis has shown that this vulnerability can only be exploited in a modified lab environment. It is unlikely to be exploited in a real life scenario with standard ssh configuration. Inclusion of ASLR techniques would further increase the difficulty of attack by several orders of magnitude. SUSE Solution Security team will continue to keep an eye on this vulnerability and any future types of Row Hammer attack vulnerabilities, as they are harder to exploit and would require special configuration cases.
