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.
