In the Linux kernel, the following vulnerability has been resolved: s390/pci: Avoid deadlock between PCI error recovery and mlx5 crdump Do not block PCI config accesses through pci_cfg_access_lock() when executing the s390 variant of PCI error recovery: Acquire just device_lock() instead of pci_dev_lock() as powerpc's EEH and generig PCI AER processing do. During error recovery testing a pair of tasks was reported to be hung: mlx5_core 0000:00:00.1: mlx5_health_try_recover:338:(pid 5553): health recovery flow aborted, PCI reads still not working INFO: task kmcheck:72 blocked for more than 122
