Integer overflow in tensor copy size calculation in Samsung Open Source ONE could lead to out of bounds access during loop state propagation. Affected version is prior to commit 1.30.0.
AnalysisAI
Integer overflow in tensor copy size calculation within Samsung Open Source ONE enables out of bounds memory access during loop state propagation. Unauthenticated local attackers with user interaction can trigger the overflow to read sensitive data, modify memory, or cause denial of service on affected versions prior to 1.30.0. CVSS 6.6 indicates moderate severity with high availability impact.
Technical ContextAI
Samsung ONE is an open-source neural network framework. The vulnerability exists in tensor copy operations where integer overflow occurs during size calculation within loop state propagation logic. When an attacker supplies a crafted tensor with specially constructed dimensions, the size calculation overflows, resulting in a smaller-than-intended buffer allocation. Subsequent copy operations then write beyond the allocated buffer boundary. This is a classic CWE-190 (Integer Overflow or Wraparound) condition combined with insufficient bounds checking on the resulting pointer arithmetic.
RemediationAI
Upgrade to Samsung Open Source ONE version 1.30.0 or later, which includes the fix via GitHub pull request #16481. Developers integrating ONE should apply this patch immediately. As a temporary workaround pending upgrade, validate tensor dimensions and copy sizes before processing untrusted tensor inputs, and implement runtime bounds checking on buffer operations. Limit tensor processing to authenticated users where feasible, and sandbox tensor processing in memory-isolated containers to contain out-of-bounds access impact. Note that workarounds do not eliminate the root cause and should be treated as interim measures only.
