Description

A flaw was found in the Linux kernel. When the damon_stat_start() function fails to complete its operation, a memory leak can occur. If a user attempts to re-enable the DAMON (Data Access MONitor) feature, previously allocated memory for the damon_ctx object is not properly deallocated, leading to a persistent memory leak. This can result in resource exhaustion over time, potentially impacting system stability.
