Privilege escalation via kernel out-of-bounds read
Published Aug 17, 2026 · Updated Aug 17, 2026
BeyondTrust Endpoint Privilege Management for Windows before 26.1.2 allows local users to escalate privileges via kernel memory corruption. BeyondTrust states that a kernel-mode component insufficiently validates input it processes, causing an out-of-bounds read and related memory corruption, but has not published a more specific locus. Exploitation requires local access and only standard non-administrative privileges on a protected endpoint; successful abuse can corrupt kernel memory, execute arbitrary code in kernel mode, and escalate privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
