Service interruption via integer-overflow frame length check
Published Mar 5, 2020 · Updated Aug 5, 2024
Integer overflow in Qualcomm Snapdragon WLAN frame-length validation allows attackers to trigger unexpected checks by sending crafted frames to affected chipsets. The length field and another 32-bit integer are added before validation, allowing arithmetic wraparound to alter the check result. The advisory does not specify whether exploitation crashes, hangs, or otherwise interrupts service, and no privilege or user interaction requirement is published.
