CVE-2026-80549 s390/vfio_ccw: Move cp cleanup out of not operational

In the Linux kernel, the following vulnerability has been resolved: s390/vfioccw: Move cp cleanup out of not operational The fsmnotoper routine is called when the device has been lost, and is by definition no longer operational. Since this can happen asynchronously from the normal behavior of the...

CVE-2026-80549

This CVE affects the s390/vfio_ccw driver in the Linux kernel. The fsm_notoper() routine is invoked when a channel-attached device is lost; because this can occur asynchronously, the cleanup of private->cp resources may execute while other locks (notably the cio subchannel lock ) are held in t...
