CVE-2020-3615Network attack vector

Wireless disruption via incorrect frame-subtype enum checks

Published Jun 2, 2020 · Updated Aug 4, 2024

Reachable assertion in Qualcomm Snapdragon WLAN firmware allows attackers to interrupt wireless connectivity with crafted management frames. The WLAN frame-subtype check compares deauthentication and disassociation frames against incorrect enum values, so valid frames are discarded during a rogue-frame stream. Exploitation requires RMF to be enabled and a rogue peer to keep sending deauthentication or disassociation frames; the documented consequence is wireless service interruption.
