In the Linux kernel, the following vulnerability has been resolved: io_uring/io-wq: check IO_WQ_BIT_EXIT inside work run loop Currently this is checked before running the pending work. Normally this is quite fine, as work items either end up blocking (which will create a new worker for other items), or they complete fairly quickly. But syzbot reports an issue where io-wq takes seemingly forever to exit, and with a bit of debugging, this turns out to be because it queues a bunch of big (2GB - 4096b) reads with a /dev/msr* file. Since this file type doesn't support ->read_iter(), loop_rw_iter() ends up handling them. Each read returns 16MB of data read, which takes 20 (!!) seconds. With a bunch of these pending, processing the whole chain can take a long time. Easily longer than the syzbot uninterruptible sleep timeout of 140 seconds. This then triggers a complaint off the io-wq exit path: INFO: task syz.4.135:6326 blocked for more than 143 seconds. Not tainted syzkaller #0 Blocked by coredump.

However, we can speed up the exit by checking the IO_WQ_BIT_EXIT inside the io_worker_handle_work() loop, as syzbot will exit the ring after queueing up all of these reads. Then once the first item is processed, io-wq will simply cancel the rest. That should avoid syzbot running into this complaint again.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - io_uring/io-wq: check IO_WQ_BIT_EXIT inside work run loop Currently this is checked before running the     pending work. Normally this is quite fine, as work items either end up blocking (which will create a new     worker for other items), or they complete fairly quickly. But syzbot reports an issue where io-wq takes     seemingly forever to exit, and with a bit of debugging, this turns out to be because it queues a bunch of     big (2GB - 4096b) reads with a /dev/msr* file. Since this file type doesn't support ->read_iter(),     loop_rw_iter() ends up handling them. Each read returns 16MB of data read, which takes 20 (!!) seconds.
    With a bunch of these pending, processing the whole chain can take a long time. Easily longer than the     syzbot uninterruptible sleep timeout of 140 seconds. This then triggers a complaint off the io-wq exit     path: INFO: task syz.4.135:6326 blocked for more than 143 seconds. Not tainted syzkaller #0 Blocked by     coredump. echo 0 > /proc/sys/kernel/hung_task_timeout_secs disables this message. task:syz.4.135 state:D     stack:26824 pid:6326 tgid:6324 ppid:5957 task_flags:0x400548 flags:0x00080000 Call Trace: <TASK>     context_switch kernel/sched/core.c:5256 [inline] __schedule+0x1139/0x6150 kernel/sched/core.c:6863

However, we can speed up the exit by checking the     IO_WQ_BIT_EXIT inside the io_worker_handle_work() loop, as syzbot will exit the ring after queueing up all     of these reads. Then once the first item is processed, io-wq will simply cancel the rest. That should     avoid syzbot running into this complaint again. (CVE-2026-23113)
