In the Linux kernel, the following vulnerability has been resolved: io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work When the sqpoll

In the Linux kernel, the following vulnerability has been resolved: io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work When the sqpoll is exiting and cancels pending work items, it may need to run task_work. If this happens from within io_uring_cancel_generic(), then it may be under waiting for the io_uring_task waitqueue. This results in the below splat from the scheduler, as the ring mutex may be attempted grabbed while in a TASK_INTERRUPTIBLE state. Ensure that the task state is set appropriately for that, just like what is done for the other cases in io_run_task_work(). do not call blocking ops when !TASK_RUNNING; state=1 set at [<0000000029387fd2>] prepare_to_wait+0x88/0x2fc WARNING: CPU: 6 PID: 59939 at kernel/sched/core.c:8561 __might_sleep+0xf4/0x140 Modules linked in: CPU: 6 UID: 0 PID: 59939 Comm: iou-sqp-59938 Not tainted 6.12.0-rc3-00113-g8d020023b155 #7456 Hardware name: linux,dummy-virt (DT) pstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) pc : __might_sleep+0xf4/0x140 lr : __might_sleep+0xf4/0x140 sp : ffff80008c5e7830 x29: ffff80008c5e7830 x28: ffff0000d93088c0 x27: ffff60001c2d7230 x26: dfff800000000000 x25: ffff0000e16b918

What it means for a small business

Linux is on the computers, phones or browsers your team uses every day. Turn on automatic updates and restart: most of these fixes only take effect after a restart.

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.18%, higher than 7% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored November 9, 2026, updated daily.

Check your own setup

Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
Server check: what your web server says about itself, and whether that version has known flaws.
