Last modified

CVE-2023-42465 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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.. EPSS estimates a 0.54% chance of exploitation in the next 30 days.
