CVE-2024-49839
Published: 03 February 2025
Summary
CVE-2024-49839 is a high-severity Buffer Over-read (CWE-126) vulnerability in Qualcomm Ar8035 Firmware. Its CVSS base score is 8.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 34.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2024-49839 is a memory corruption vulnerability stemming from a mismatch in the T2LM information element during management frame processing. It affects components in Qualcomm products, as detailed in their security bulletin. The issue is associated with CWE-126 (Buffer Over-read) and CWE-125 (Out-of-bounds Read), earning a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L), indicating high severity due to its network accessibility and potential for significant confidentiality impact.
A remote, unauthenticated attacker can exploit this vulnerability by sending crafted management frames over the network with low complexity and no user interaction required. Successful exploitation could result in high-impact confidentiality violations, such as disclosure of sensitive information through memory corruption, alongside a low-impact availability disruption, potentially enabling denial-of-service conditions.
Qualcomm's February 2025 security bulletin at https://docs.qualcomm.com/product/publicresources/securitybulletin/february-2025-bulletin.html provides details on affected products and recommended mitigations or patches.
