Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Secure Channel allows an authorized attacker to elevate privileges locally.

The remote Windows host is missing security update 5055527. It is, therefore, affected by multiple vulnerabilities

  - Use after free in Windows Win32K - GRFX allows an unauthorized attacker to elevate privileges over a     network. (CVE-2025-26687)   
  - A remote code execution vulnerability. An attacker can exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2025-27481)   
  - An elevation of privilege vulnerability. An attacker can exploit this to gain elevated privileges. (CVE-2025-27740)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
