CVE-2023-53511

A flaw was found in the Linux kernel. A local user can exploit a file descriptor leak in the io_uring subsystem when performing operations on filesystems that do not support nowait buffered read, such as ocfs2. This vulnerability occurs because a file descriptor (fget) is acquired but not properly released (fput), leading to a resource leak. The most important consequence is a Denial of Service (DoS), which can prevent the unmounting of affected filesystems.
