CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-21475 is a high-severity Use of Out-of-range Pointer Offset (CWE-823) vulnerability in Qualcomm 315 5G Iot Modem Firmware. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked at the 1th 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.

V1.4.1
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including static analysis and fuzzing) directly finds unsafe pointer arithmetic before deployment.
Requiring documented development standards and tools can mandate safe pointer usage and compiler/runtime checks that stop the weakness from being introduced.
Security engineering principles can require bounds-checked pointer arithmetic or safe language constructs that structurally avoid out-of-range offsets.
Process isolation confines damage from invalid pointer offsets to a single address space, reducing overall impact.
Input validation directly enforces bounds checking that stops out-of-bounds reads/writes from being introduced or reached.
Memory-protection controls limit the blast radius of an out-of-range pointer dereference without preventing or detecting the coding error itself.

Secure SDLC mandates input validation and bounds checking that can prevent out-of-range pointer offsets.
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.
Secure coding standards directly forbid unsafe pointer arithmetic and require bounds checks.
Security testing can detect out-of-range pointer offsets before release.
