CVE-2022-48462

Local service interruption via unchecked buffer copy

Published Dec 4, 2023 · Updated Aug 3, 2024

Out-of-bounds write in the Unisoc Android Wi-Fi service allows local users to interrupt Wi-Fi operation through an unchecked buffer copy. The service copies input into a memory buffer without checking its size, allowing a write beyond the buffer boundary. Local access is required, and the documented consequence is service interruption without additional execution privileges.
