Summary

CVE-2025-47370 is a medium-severity Reachable Assertion (CWE-617) vulnerability in Qualcomm Ar8035 Firmware. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 2th 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-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds reachable assertions during development.

Security engineering principles discourage use of assertions for handling untrusted input.

Validating untrusted inputs structurally prevents attacker data from reaching and triggering assertions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent unsafe assertions from being coded in reachable paths.

DE.CM-09 partial match
prevents

Runtime monitoring of software can detect assertion-triggered crashes as adverse events.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover and record reachable-assertion flaws before deployment.

finds

Security testing in development can detect reachable assertions before release, reducing the likelihood of exploitation.

prevents

Secure development lifecycle mandates defensive coding and input validation that prevent reachable assertions from being triggered by untrusted data.

prevents

Application security requirements can specify that assertions must not be reachable from attacker-controlled inputs.

prevents

Secure architecture principles discourage the use of assertions for runtime error handling that an attacker could exploit.

prevents

Secure coding standards explicitly ban the use of assert() or equivalent statements that can be triggered by external input.
