CVE-2023-43532
Qualcomm Fastconnect 6700 Firmware
Raw vector
CVSS:3.1/AV:L/AC:L/PR:N/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-2023-43532 is a high-severity Untrusted Pointer Dereference (CWE-822) vulnerability in Qualcomm Fastconnect 6700 Firmware. Its CVSS base score is 8.4 (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 SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover instances where untrusted data is turned into a pointer and dereferenced.
Validating all information inputs stops untrusted values from being accepted and converted into dereferenceable pointers.
Documented development standards and tools can mandate safe memory-management idioms and static checks that avoid invalid releases.
An SDLC that incorporates security can embed memory-safety requirements, reducing the chance such coding errors are introduced.
Engineering principles require correct resource management and memory-release patterns that stop invalid pointer releases from being coded.
Memory-protection mechanisms limit the damage from an invalid pointer dereference without stopping the root coding flaw.

Runtime monitoring of software and data can detect adverse events resulting from exploitation of the weakness.
Vulnerability identification processes can discover instances of this weakness via code review or scanning.
Secure SDLC practices directly prevent introduction of untrusted pointer handling during development.
