Summary

CVE-2023-43553 is a critical-severity Use of Out-of-range Pointer Offset (CWE-823) vulnerability in Qualcomm Ar8035 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 27th 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 SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including static analysis and fuzzing) directly finds unsafe pointer arithmetic before deployment.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented development standards and tools can mandate safe pointer usage and compiler/runtime checks that stop the weakness from being introduced.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles can require bounds-checked pointer arithmetic or safe language constructs that structurally avoid out-of-range offsets.

SC-39 Process Isolation partial match

Process isolation confines damage from invalid pointer offsets to a single address space, reducing overall impact.

SI-16 Memory Protection partial match

Memory-protection controls limit the blast radius of an out-of-range pointer dereference without preventing or detecting the coding error itself.

ID.RA-01 partial match
blocks

SAST/DAST tools used for vulnerability identification can surface this class of coding defect.

PR.PS-06 partial match
blocks

Secure SDLC practices directly require bounds-checked pointer arithmetic and static analysis to prevent out-of-range offsets.

A.5.16 Identity management partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure SDLC mandates input validation and bounds checking that can prevent out-of-range pointer offsets.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against buffer overflows or SQL injections) be identified and specified during development or acquisition; it does not itself enforce, implement, or prevent out-of-range pointer arithmetic in the resulting application.

A.8.27 Secure system architecture and engineering principles partial match
removes
A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid unsafe pointer arithmetic and require bounds checks.

A.8.29 Security testing in development and acceptance partial match
finds

Security testing can detect out-of-range pointer offsets before release.
