CVE-2026-80548

A flaw was found in the Linux kernel's s390/vfioccw component. The iomutex was not sufficiently expanded to serialize I/O operations, which could lead to race conditions. These race conditions could result in unexpected system behavior or instability. Mitigation This flaw can only be triggered...

CVE-2026-80548

CVE-2026-80548 affects the Linux kernel s390/vfio_ccw subsystem, where the io_mutex lock had a scope too narrow to fully serialize I/O operations, leaving residual race conditions on I/O resources. The fix expands the lock's scope to close these windows and also reworks how cp_free() is invoked f...
