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

CVE-2024-46922 is a vulnerability affecting Samsung Mobile Processor Exynos 1480 and 2400 chips, stemming from the absence of a null pointer check in the amdgpu_cs_parser_bos function within the Xclipse Driver. This flaw, classified under CWE-476 (NULL Pointer Dereference), was publicly disclosed on February 12, 2025, and carries a CVSS v3.1 base score of 7.5, indicating high severity primarily due to its potential for disruption.

Remote attackers require no privileges or user interaction to exploit this issue over the network with low attack complexity. Successful exploitation triggers a denial-of-service condition by crashing the affected driver component, resulting in high availability impact without compromising confidentiality or integrity.

Samsung has published details on this vulnerability through its product security updates portal at https://semiconductor.samsung.com/support/quality-support/product-security-updates/, where practitioners can find guidance on applicable patches or mitigations for affected Exynos-based devices.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation (including static analysis) directly finds null-dereference bugs before deployment.

Documented development standards and tools can enforce null-safety rules and safe pointer usage.

Engineering principles can mandate defensive coding such as explicit null checks before dereference.
