CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2023-41056 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Redis Redis. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 16% of CVEs by exploit likelihood; 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 SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Redis is an in-memory database that persists on disk and is affected by an integer overflow vulnerability (CWE-190) that occurs during memory buffer resizing. The flaw produces a heap overflow that can lead to remote code execution. It impacts versions prior to the fixes released in 7.0.15 and 7.2.4 and carries a CVSS 3.1 score of 8.1.
An unauthenticated network attacker can trigger the condition without user interaction, although successful exploitation requires high attack complexity. If achieved, the attacker obtains the ability to execute arbitrary code on the Redis host, resulting in full confidentiality, integrity, and availability impact.
The official GitHub security advisory and release notes for 7.0.15 and 7.2.4 state that the issue has been resolved by correcting buffer-resizing logic. Downstream distributions such as Fedora have published corresponding package updates. The associated EPSS score has remained low, moving only from 0.0732 to a peak of 0.0751 with no material upward trajectory after disclosure.

Vulnerability Data
Redis is an in-memory database that persists on disk. Redis incorrectly handles resizing of memory buffers which can result in integer overflow that leads to heap overflow and potential remote code execution. This issue has been patched in version 7.0.15…

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.
Documented development standards and tools can enforce or check for correct pairing of allocators and deallocators.
Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.
Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

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

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.
