Summary

CVE-2024-49838 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 OS Credential Dumping (T1003); ranked at the 18th 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.

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

CVE-2024-49838 is an information disclosure vulnerability that arises while parsing the OCI IE with an invalid length, associated with CWE-126 (Buffer Over-read) and CWE-125 (Out-of-bounds Read). It carries 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 significant confidentiality impact. The vulnerability affects components documented in Qualcomm's security advisories.

A remote, unauthenticated attacker can exploit this vulnerability over the network with low attack complexity and no user interaction required. By sending a specially crafted input with an invalid length in the OCI IE, the attacker can trigger the parsing flaw, resulting in disclosure of sensitive information (high confidentiality impact) alongside a low availability impact from potential denial of service.

Qualcomm's February 2025 security bulletin, available at https://docs.qualcomm.com/product/publicresources/securitybulletin/february-2025-bulletin.html, addresses this CVE with details on affected products and recommended mitigations or patches.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (static analysis, fuzzing, bounds checking tests) directly finds buffer over-read flaws.

Engineering principles such as memory-safe design and bounds-checked abstractions structurally stop introduction of out-of-bounds reads.

Process isolation limits the blast radius of an over-read to the compromised domain.

Input validation enforces length and index constraints that prevent many externally triggered over-reads.

finds

Security testing in development can detect buffer over-reads before release.

A.8.15 Logging partial match
finds

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure SDLC mandates input validation and bounds checking that can prevent buffer over-reads.

prevents

Application security requirements can specify buffer-size and bounds-checking rules.

prevents

Secure architecture principles include memory-safety and bounds-checking design choices.

prevents

Secure coding standards directly require bounds-checked buffer access, mitigating over-reads.
