CVE-2024-49843 is a high-severity Improper Validation of Array Index (CWE-129) vulnerability in Qualcomm Fastconnect 6200 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 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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-2024-49843 is a memory corruption vulnerability stemming from improper validation of array index (CWE-129) during the processing of IOCTL calls from user space intended to handle GPU AHB bus errors. It affects Qualcomm components, as detailed in the vendor's security bulletin.

The vulnerability 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 exploitation requires local access with low privileges and low complexity, with no user interaction needed. A malicious local user could send a crafted IOCTL request, triggering memory corruption that enables high-impact compromise of confidentiality, integrity, and availability, such as arbitrary code execution or system crashes.

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