Description OSIDB Bzimport 2025-12-24 14:05:53 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ipc: mqueue: fix possible memory leak in init_mqueue_fs()

commit db7cfc380900 ("ipc: Free mq_sysctls if ipc namespace creation
failed")

Here's a similar memory leak to the one fixed by the patch above.
retire_mq_sysctls need to be called when init_mqueue_fs fails after
setup_mq_sysctls.
