Memory disclosure via integer overflow
Published Jul 8, 2025 · Updated Feb 13, 2026
Integer overflow in Windows Hyper-V before build 10.0.26100.4652 allows remote authenticated users to disclose memory over an adjacent network. Microsoft identifies a wraparound followed by an out-of-bounds read but has not published the affected Hyper-V routine or malformed field. Exploitation requires low privileges and adjacent-network reachability; the reported impact is memory disclosure without modification or service interruption.
