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

CVE-2024-38413 is a memory corruption vulnerability that occurs while processing frame packets in Qualcomm components. It is linked to CWE-20 (Improper Input Validation) and CWE-787 (Out-of-bounds Write), with 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). The vulnerability was published on 2025-02-03.

An attacker with local access and low privileges (PR:L) can exploit this issue with low attack complexity and no user interaction required. Exploitation allows limited impact on confidentiality (C:L), high impact on integrity (I:H), and limited impact on availability (A:L), within the unchanged security scope.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing input validation through analysis or test cases.

SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.

Requiring documented development standards and tools can embed input-validation practices into the engineering process.

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

finds

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.

prevents

Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.

prevents

Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.

prevents

Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.

prevents

Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.

prevents

Change management can enforce review gates that catch unsafe memory operations before deployment.
