Kernel code execution via ISO integer overflow
Published Oct 11, 2022 · Updated Aug 27, 2025
Integer overflow in Microsoft Windows CDFS allows remote attackers to execute kernel code when a target opens a crafted ISO file. CDFS fails to validate user-supplied ISO metadata before using an overflowed integer to size a buffer, permitting memory corruption during parsing. Exploitation requires user interaction with a malicious page or file and runs attacker-controlled code in the kernel context.

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.
