kernel: io_uring/rw: defer fsnotify calls to task context

A locking context violation was found in the Linux kernel's iouring subsystem. The fsnotify calls were being made directly from kiocb completion context, which can execute in soft or hard IRQ context. This causes lockdep warnings when fsnotify attempts memory allocation with GFPKERNEL flags, whic...

kernel: Linux kernel: Denial of Service in io_uring due to hung task detection

A flaw was identified in the Linux kernel’s iouring subsystem related to how request completions are handled when an iouring instance exits. During cleanup, the function ioringexitwork was waiting in an uninterruptible state for request completions. Under certain test and signal conditions e.g.,...

kernel: Linux kernel: Denial of Service due to file descriptor leak in io_uring with ocfs2

A flaw was found in the Linux kernel. A local user can exploit a file descriptor leak in the iouring 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...

kernel: Linux kernel: Denial of Service due to improper io_uring/af_unix file cleanup

A flaw was found in the Linux kernel's iouring/afunix component. A local user could exploit improper handling of registered files during garbage collection. This vulnerability can lead to a memory leak, potentially causing a denial of service DoS on the system...
