CVE-2026-74645

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A division by zero error can be triggered in the damos quota score() function. This occurs when the active mem bp parameter is set to a value greater than 10000, specifically 10002, which results in the cold memory scheme's quota goal target value becoming zero. Exploiting this issue requires write permissions for module parameters.

Recommendations Avoid setting the active mem bp parameter to a value greater than 10000. Restrict write access to module parameters to prevent unauthorized modification of the active mem bp variable.
