CVE-2024-31146

Disclosure Date: September 25, 2024
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

When multiple devices share resources and one of them is to be passed
through to a guest, security of the entire system and of respective
guests individually cannot really be guaranteed without knowing
internals of any of the involved guests. Therefore such a configuration
cannot really be security-supported, yet making that explicit was so far
missing.

Resources the sharing of which is known to be problematic include, but
are not limited to

  • – PCI Base Address Registers (BARs) of multiple devices mapping to the
    same page (4k on x86),
  • – INTx lines.
