CVE-2026-98474

The Linux kernel contains a vulnerability in the s390/pci subsystem where the zpci_report_status() function fails to hold the necessary device lock when accessing a device's driver (specifically when pdev is non-NULL). This missing lock can lead to inconsistent states during recovery. The fix inv...
