CVE-2022-47368

WLAN service interruption via unchecked driver parameters

Published Feb 6, 2023 · Updated Mar 26, 2025

Out-of-bounds write in the WLAN driver on UNISOC Android 10 through 12 chipsets allows local users to interrupt WLAN services. The driver fails to validate parameters before using them for a memory write, but UNISOC has not disclosed the affected function or parameter structure. Reaching the flaw requires high local privileges; the reported consequence is WLAN-service interruption, with limited confidentiality and integrity impact also reflected in the vendor assessment.
