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

Description A memory leak issue has been identified in the Linux kernel, specifically in the watch queue component. The problem arises when the watch queue is dismantled, and the page array is not properly freed. This results in an unreferenced object, leading to a memory leak. The issue is triggered by a series of function calls, including watch queue set size(), pipe ioctl(), vfs ioctl(), and do sys ioctl(). The memory leak can cause problems, such as increased memory usage over time.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
