AI-suggested
A patch is available and has been applied in the Linux kernel commits referenced. Users and administrators should update to the fixed Linux kernel version or apply the relevant patches to ensure the device lock is properly held in zpci_report_status(). Since this is a kernel-level fix, updating the kernel is the recommended remediation.
Description
A vulnerability in the Linux kernel's s390/pci subsystem was fixed by adding a missing device lock in the zpci_report_status() function. The issue involved accessing the device's driver without holding the necessary device lock when pdev is non-NULL, potentially causing inconsistent device state during recovery. The fix expands the device lock critical section and adds a lockdep assertion to ensure proper locking.
