Memory corruption via unchecked tensor size multiplication
Published Apr 22, 2026 · Updated Apr 22, 2026
Integer overflow in ONE before 1.30.0 allows local users to trigger out-of-bounds memory access by processing a large tensor. BuddyMemoryManager and multiple luci-interpreter kernels multiply a 32-bit element count by element size without checking for overflow. User interaction is required to process a crafted large tensor, after which memory access can extend beyond the undersized buffer.

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.
