Summary

CVE-2024-38412 is a medium-severity Use After Free (CWE-416) vulnerability in Qualcomm Fastconnect 7800 Firmware. Its CVSS base score is 6.6 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); 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-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

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

CVE-2024-38412 is a memory corruption vulnerability classified under CWE-416 (Use After Free), occurring while invoking IOCTL calls from user-space to kernel-space to handle session errors. It affects Qualcomm components, as documented in their security advisories.

The vulnerability carries a CVSS v3.1 base score of 6.6 (AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L). A local attacker with low privileges can exploit it with low attack complexity and no user interaction required. Successful exploitation enables low-impact confidentiality and availability violations alongside high-impact integrity violations, potentially allowing data tampering or limited code execution in kernel space.

Qualcomm's February 2025 security bulletin, available at https://docs.qualcomm.com/product/publicresources/securitybulletin/february-2025-bulletin.html, details affected products and recommends applying available patches for mitigation.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover use-after-free bugs through dynamic analysis or fuzzing.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can require memory-safe constructs or languages that structurally avoid introducing use-after-free.

SC-39 Process Isolation partial match

Process isolation confines the blast radius of use-after-free memory corruption to a single execution domain.

SI-16 Memory Protection partial match

Memory protection controls limit exploitation impact by blocking unauthorized code execution from dangling pointers.
