This vulnerability (CWE-416) involves a use-after-free condition in the Windows USB Print Driver component of Windows 11 Version 24H2 (build 10.0.26100.0). Exploitation requires physical access and can result in privilege escalation by an unauthorized attacker. The vulnerability has been assigned CVE-2026-55000 and has a CVSS 3.1 base score of 6.4 with attack vector requiring physical access, high attack complexity, no privileges required, and no user interaction. Microsoft has published an official fix to address this issue.

Successful exploitation allows an attacker with physical access to the affected system to elevate privileges, potentially gaining higher-level access than intended. This could compromise system integrity and confidentiality. The attack complexity is high and requires physical presence, limiting remote exploitation.

An official fix is available from Microsoft. Users and administrators should apply the security update provided in the Microsoft advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-55000 to remediate this vulnerability.
