Summary

CVE-2024-43055 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Qualcomm Fastconnect 6900 Firmware. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); 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 SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-43055 is a memory corruption vulnerability (CWE-120) triggered during the processing of camera use case IOCTL calls in Qualcomm components. It carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high potential impact with local access required.

A local attacker possessing low privileges can exploit this issue with low attack complexity and without requiring user interaction. Exploitation enables high confidentiality, integrity, and availability impacts, such as unauthorized data access, modification, or denial of service through memory corruption.

Qualcomm's March 2025 Security Bulletin provides details on affected products, patches, and mitigation guidance; see https://docs.qualcomm.com/product/publicresources/securitybulletin/march-2025-bulletin.html for implementation steps.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis can find missing size checks before deployment.

Input validation directly enforces size checks before buffer copies.

Engineering principles require bounds checking and safe buffer handling in design.

Memory protection limits the impact of an overflow once it occurs.

prevents

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.

finds

Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.

prevents

Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.

prevents

Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.

prevents

Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
