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

Description A memory leak exists in the init mqueue fs() function within the message queue subsystem of the Linux kernel. The issue occurs when init mqueue fs fails after setup mq sysctls, and retire mq sysctls is not called, leading to a potential memory leak. The commit db7cfc380900 addresses this by ensuring mq sysctls are freed if the IPC namespace creation fails.
