CVSS 3.1
7.0 highCVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:HCVE-2023-42465
High (7.0) in sudo project sudo. EPSS 0.5% chance of exploitation in the next 30 days.
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.
