CVE-2022-50284 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ipc: fix memory leak in init_mqueue_fs() When setup_mq_sysctls() failed in init_mqueue_fs(), mqueue_inode_cachep is not released. In order to fix this issue, the release path is reordered.
A memory leak vulnerability has been identified in the Linux kernel's inter-process communication (IPC) subsystem, specifically within the message queue (mqueue) initialization process. When the function 'setup_mq_sysctls()' fails during the 'init_mqueue_fs()' execution, the 'mqueue_inode_cachep' is not properly released, leading to a memory leak. This issue has been addressed by reordering the release process to ensure proper memory management.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation.
