The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - PCI: host-generic: Fix NULL pointer dereference on 32-bit CAM systems On 32-bit systems the config space     is too large to ioremap in one go, so pci_ecam_create() maps each bus segment separately and relies on the
    ->add_bus callback (pci_ecam_add_bus) to populate the per-bus mapping in cfg->winp[]. pci_ecam_map_bus()     then uses that mapping as the base for every config access. The generic ECAM ops (pci_generic_ecam_ops)     already provide the ->add_bus and ->remove_bus callbacks, but the CAM (legacy) ops in pci-host-generic.c     do not. As a result, on a 32-bit host using pci-host-cam-generic the per-bus mapping is never set up and     the first config read dereferences a NULL base, crashing during bus enumeration: Unable to handle kernel     NULL pointer dereference at virtual address 00000800 Oops [#1] CPU: 0 PID: 1 Comm: swapper Not tainted     6.9.7+ #43 Hardware name: Digilent Nexys-Video-A7 RV32 (DT) epc : pci_generic_config_read+0x40/0xb0 ra :

Since pci_ecam_add_bus() and pci_ecam_remove_bus() are static to     ecam.c, move the CAM ops definition there as pci_generic_cam_ops (mirroring pci_generic_ecam_ops) and     export it for pci-host-generic.c to reference.
