CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2026-53482 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Dell Data Domain Operating System. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 30th 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 AC-3 (Access Enforcement) and SC-7 (Boundary Protection) — see the control section below for these in your framework.

Why these techniques?
Remote unauthenticated integer overflow leading to denial of service directly maps to application-layer exploitation causing endpoint DoS (T1499.004).

Mitigating Controls (NIST 800-53 r5) AI
Boundary protection at network perimeters can block unauthenticated remote traffic to the vulnerable Data Domain management interfaces before an integer-overflow DoS can be triggered.
Access enforcement denies unauthenticated subjects any interaction with the affected service, directly preventing exploitation of the integer-overflow flaw.
Timely application of vendor patches eliminates the integer-overflow vulnerability in Dell PowerProtect Data Domain releases.

Security testing in development can detect integer overflows before release.
Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.
Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.
Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.
Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
