CVE-2026-80549

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> s390/vfio_ccw: Move cp cleanup out of not operational<br /> <br /> The fsm_notoper() routine is called when the device has been<br /> lost, and is (by definition) no longer operational. Since this<br /> can happen asynchronously from the normal behavior of the<br /> driver, the cleanup may happen when holding other locks<br /> in the calling sequence (notably, the cio subchannel lock).<br /> <br /> Push the cleanup of the private-&gt;cp resources to a workqueue,<br /> where it can be done out from under that lock sequence and<br /> a future patch can safely manage the locking requirements.
