Описание

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.

A flaw was found in the Linux kernel's mqueue (message queue) component. A local attacker with low privileges could exploit a memory leak in the init_mqueue_fs() function. This vulnerability occurs when retire_mq_sysctls is not called after setup_mq_sysctls fails, leading to resource exhaustion. This could result in a Denial of Service (DoS) condition, making the system unavailable.
