Summary

CVE-2026-40448 is a medium-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Samsung One. Its CVSS base score is 5.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked at the 3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires applying the vendor fix (commit 1.30.0) that eliminates the integer-overflow path in tensor size calculation.

prevent

Mandates developer security testing (fuzzing, bounds analysis, static analysis) that would have detected the CWE-190 flaw before release.

prevent

Requires validation of untrusted size parameters used in tensor allocation, limiting the values that can trigger the overflow.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require use of safe arithmetic, bounds checks, and testing that prevent integer overflows.

detects

Security testing in development can detect integer overflows before release.

prevents

Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.

degrades

Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.

degrades

Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.

prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
