Service interruption via overflowing tensor allocation
Published Apr 22, 2026 · Updated Apr 22, 2026
Integer overflow in tensor allocation sizing in Samsung Open Source ONE before commit 95fba2d allows local users to disrupt inference. BuddyMemoryManager and the ExpandDims, If, Reshape, and TransposeConv kernels use 32-bit element counts without overflow validation, so large tensor dimensions can wrap before allocation. Exploitation requires user interaction to process a crafted large model, yielding an undersized buffer that can corrupt results or interrupt the service.

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.
