Description
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel before 5.3.9, 4.19.82, 4.14.152, 4.9.199, 4.4.199 lacks a certain upper-bound check, leading to a buffer overflow. An attacker is able to trigger the overflow remotely through Wi-Fi by using a power-saving feature known as a Notice of Absence when the Realtek (RTLWIFI) driver is being used on the affected host leading to arbitrary code execution.
