Linux Kernel DAMON Online Parameters Commit Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's DAMON (Data Access Monitoring) subsystem. The issue arises in the sysfs interface, where the context used for testing online DAMON parameter commits is only deallocated if the test fails. As a result, memory is leaked for each successful commit. This vulnerability affects Linux kernel versions 6.15 and later.

Impact

Exploitation of this vulnerability leads to a memory leak, causing increased memory usage over time.

Remediation

The vulnerability has been addressed in the official Linux Git repository. Users can download the patched version from the Linux kernel stable tree.
