Improper authorization in Windows Kerberos allows an authorized attacker to elevate privileges over an adjacent network.
Technical Analysis
CVE-2026-27912 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.0.
