CVE-2026-68588 · Severity: info · Published 2026-11-02

A vulnerability in MediaTek modem firmware could allow an attacker operating a rogue cellular base station to crash or disable a connected device, causing a denial of service. The flaw stems from improper handling of numeric values in the modem's signal processing code. An attacker would need only to position their equipment to intercept the target device's cellular connection, with no user interaction required to trigger the attack.
