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: vfio/pci: Properly hide first-in-list
PCIe extended capability There are cases where a PCIe extended capability should be hidden from the user.
For example, an unknown capability (i.e., capability with ID greater than PCI_EXT_CAP_ID_MAX) or a
capability that is intentionally chosen to be hidden from the user. Hiding a capability is done by
virtualizing and modifying the 'Next Capability Offset' field of the previous capability so it points to
the capability after the one that should be hidden. The special case where the first capability in the
list should be hidden is handled differently because there is no previous capability that can be modified.
In this case, the capability ID and version are zeroed while leaving the next pointer intact. This hides
the capability and leaves an anchor for the rest of the capability list. However, today, hiding the first
capability in the list is not done properly if the capability is unknown, as struct
vfio_pci_core_device->pci_config_map is set to the capability ID during initialization but the capability
ID is not properly checked later when used in vfio_config_do_rw(). This leads to the following warning [1]
and to an out-of-bounds access to ecap_perms array. Fix it by checking cap_id in vfio_config_do_rw(), and
if it is greater than PCI_EXT_CAP_ID_MAX, use an alternative struct perm_bits for direct read only access
instead of the ecap_perms array. Note that this is safe since the above is the only case where cap_id can
exceed PCI_EXT_CAP_ID_MAX (except for the special capabilities, which are already checked before). [1]
