An out-of-bounds (OOB) memory write flaw exists in the `watch queue` event notification subsystem. This issue allows a local user to overwrite parts of the kernel state, which can lead to a denial of service or the acquisition of privileged access, such as root privileges. Technical exploitation may involve using PageJack to create a page-level Use-After-Free (UAF), a condition where the system continues to use a pointer after the memory it points to has been freed, to overwrite the `struct file` for local privilege escalation.
