A vulnerability exists in the Linux kernel 's iio: trigger subsystem. The function iio_trigger_notify_done_atomic() defers reenable() into trig->reenable_work on the system workqueue, where a worker dereferences the owning trigger using container_of(). Because this work is not cancelled before...

Linux Kernel Security Vulnerabilities

There are security vulnerabilities in Linux kernels versions 5.15.17 to 5.16, 5.16.3 to 5.17, and 5.17 itself. These vulnerabilities stem from the iio trigger not canceling reenablework before releasing the trigger. The worker that was last started via an ongoing IRQ can continue to run after...
