CVE-2023-42465  (opens in a new tab)
CWE-1319  (opens in a new tab)

How to fix?

Upgrade RHEL:8 sudo to version 0:1.9.5p2-1.el8_8 or higher.
This issue was patched in RHSA-2024:0811.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sudo package and not the sudo package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
