CVE-2025-38651

Name of the Vulnerable Software and Affected Versions: Linux kernel versions 6.16.0-rc1-dev-00001-g314a2f98b65f and earlier

Description: A flaw was identified in the Linux kernel related to landlock functionality. Specifically, the get id range() function was susceptible to receiving a zero value as its first argument due to the behavior of get random u8(), while expecting a positive value. This issue was detected through KUnit tests, which triggered a warning. The problem was addressed by clamping the input value to ensure it remains positive.

Recommendations: Update to a newer version of the Linux kernel to address this issue.
