Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: PCI: Add missing bridge lock to
pci_bus_lock() One of the true positives that the cfg_access_lock lockdep effort identified is this
sequence: WARNING: CPU: 14 PID: 1 at drivers/pci/pci.c:4886 pci_bridge_secondary_bus_reset+0x5d/0x70 RIP:
0010:pci_bridge_secondary_bus_reset+0x5d/0x70 Call Trace: <TASK> ? __warn+0x8c/0x190 ?

pci_reset_bus+0x1d8/0x270 vmd_probe+0x778/0xa10 pci_device_probe+0x95/0x120 Where pci_reset_bus() users
are triggering unlocked secondary bus resets. Ironically pci_bus_reset(), several calls down from
pci_reset_bus(), uses pci_bus_lock() before issuing the reset which locks everything *but* the bridge
itself. For the same motivation as adding: bridge = pci_upstream_bridge(dev); if (bridge)
pci_dev_lock(bridge); to pci_reset_function() for the "bus" and "cxl_bus" reset cases, add pci_dev_lock()
for @bus->self to pci_bus_lock(). [bhelgaas: squash in recursive locking deadlock fix from Keith Busch:
