CVE-2022-47458

Local WLAN service interruption via unchecked parameters

Published Mar 7, 2023 · Updated Mar 5, 2025

Out-of-bounds read in Unisoc Android 10 through 12 WLAN drivers allows local users to interrupt WLAN services via unchecked parameters. The driver processes parameters without the required validation and reads beyond the intended buffer; Unisoc has not identified the affected function or parameter. A local low-privileged context is required, and the published consequence is interruption of WLAN services; no further impact is described.
