CVE-2024-31146
Last modified
CVE-2024-31146 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
