CVSS 3.1
7.4 highCVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2025-59033
High (7.4). EPSS 0.3% chance of exploitation in the next 30 days.
The Microsoft vulnerable driver block list is implemented as Windows Defender Application Control (WDAC) policy. Entries that specify only the to-be-signed (TBS) part of the code signer certificate are properly blocked, but entries that specify the signing certificate's TBS hash along with a 'FileAttribRef' qualifier (such as file name or version) may not be blocked, whether hypervisor-protected code integrity (HVCI) is enabled or not. NOTE: The vendor disputes this CVE ID assignment and states that the driver blocklist is intended for use with HVCI.
