CVE-2023-42465 Information

Description

Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value) and because the values do not resist flips of a single bit.
