In the Linux kernel, the following vulnerability has been resolved:
fs/aio: Restrict kiocb_set_cancel_fn() to I/O submitted via libaio
If kiocb_set_cancel_fn() is called for I/O submitted via io_uring, the following kernel warning appears:
WARNING: CPU: 3 PID: 368 at fs/aio.c:598 kiocb_set_cancel_fn+0x9c/0xa8 Call trace: kiocb_set_cancel_fn+0x9c/0xa8 ffs_epfile_read_iter+0x144/0x1d0 io_read+0x19c/0x498 io_issue_sqe+0x118/0x27c io_submit_sqes+0x25c/0x5fc __arm64_sys_io_uring_enter+0x104/0xab0 invoke_syscall+0x58/0x11c el0_svc_common+0xb4/0xf4 do_el0_svc+0x2c/0xb0 el0_svc+0x2c/0xa4 el0t_64_sync_handler+0x68/0xb4 el0t_64_sync+0x1a4/0x1a8
Fix this by setting the IOCB_AIO_RW flag for read and write I/O that is submitted by libaio.
