CVE-2022-26357 (GCVE-0-2022-26357)
Vulnerability from cvelistv5 – Published: 2022-04-05 00:00 – Updated: 2024-08-03 05:03
VLAI?
Summary
race in VT-d domain ID cleanup Xen domain IDs are up to 15 bits wide. VT-d hardware may allow for only less than 15 bits to hold a domain ID associating a physical device with a particular domain. Therefore internally Xen domain IDs are mapped to the smaller value range. The cleaning up of the housekeeping structures has a race, allowing for VT-d domain IDs to be leaked and flushes to be bypassed.
Severity ?
No CVSS data available.
