**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a memory leak in the Linux kernel, specifically in the sched/deadline module. The leak occurs when the `start dl timer()` function increments the `task struct` reference count and sets a timer, but the timer callback `dl task timer` does not decrement the reference count when the timer is canceled by `enqueue task dl()`. This leads to a memory leak, which can cause issues with system performance and stability. The leak was detected using the `kmemleak` tool during a stress test with `stress-ng`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
