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 kernel/irq/irqdomain.c file. The problem occurs when using the debugfs lookup() function without properly calling dput() on the result, leading to memory leaks over time. To address this, the debugfs lookup and remove() function can be used instead, as it handles the necessary logic.

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