Description
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.

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a possible memory leak in the Linux kernel's IPC (inter-process communication) message queue subsystem. Specifically, if the initialization of the message queue filesystem (init_mqueue_fs) fails after setting up system controls (mq_sysctls), the cleanup function retire_mq_sysctls is not called, leading to a memory leak.
How can this vulnerability impact me? :
The memory leak could lead to increased memory usage over time, potentially degrading system performance or causing resource exhaustion if the failure condition occurs repeatedly.
