Persistent denial of service via PE relocation-table parsing
Published May 9, 2023 · Updated Jul 10, 2025
Integer overflow in Windows kernel PE parsing allows context-dependent attackers to cause persistent service interruption via a crafted file. The relocation-table parser uses an overflowable calculation to bounds-check attacker-controlled PE data before reading memory. Exploitation requires a target to visit a malicious page or open the file, and the resulting denial of service persists across restarts.

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.
