NVD Description

See How to fix? for SLES:15.2 relevant fixed versions and status.
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.
