Описание

In the Linux kernel, the following vulnerability has been resolved: s390/vfio_ccw: Cancel existing workqueues The initialization of the io_work and crw_work workqueues begs the question of whether they should be un-initialized. Add the corresponding cleanup tags in _release_dev to ensure work isn't dispatched after the private struct is free'd.

A flaw was found in the s390/vfio_ccw component of the Linux kernel. This vulnerability arises from the improper management of workqueues, where existing tasks might not be canceled before associated resources are released. A local attacker could potentially leverage this issue to trigger a use-after-free condition, which may result in system instability or a denial of service.
