WLAN service interruption via integer overflow
Published Jan 4, 2023 · Updated Apr 10, 2025
Integer overflow in Unisoc chipset WLAN firmware on Android 10 through 12 allows local users to interrupt WLAN services via unspecified input. The WLAN driver omits a bounds check around an undisclosed integer operation, permitting overflow; the affected function and input field are not public. Local access is required, and official assessments disagree on whether prior privileges are needed and whether confidentiality or integrity can be affected.
