CVSS 7.0 · High EPSS 0,26%

Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') pada xen, debian linux +1 lainnya. Skor CVSS 3.1 7.0 (High) menurut NVD.

Deskripsi (NVD)

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.
