CVE-2023-37377

Incorrect packet filtering via inconsistent length parameters

Published Sep 8, 2023 · Updated Sep 26, 2024

Input-validation flaw in Samsung Exynos 980, 850, 1080, 2100, and W920 allows local users to cause incorrect packet filtering. The processor implementation mishandles inconsistent packet-length parameters; Samsung has not disclosed the affected routine or the exact wrong operation. The vendor assessment requires high privileges and user interaction, and the documented consequence is limited to incorrect filtering.
