Arch Linux Security Advisory ASA-201911-9
Date : 2019-11-07
CVE-ID : CVE-2019-17666
Package : linux-hardened
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1063
The package linux-hardened before version 5.3.7.b-1 is vulnerable to
arbitrary code execution.
Upgrade to 5.3.7.b-1.
# pacman -Syu "linux-hardened>=5.3.7.b-1"
The problem has been fixed upstream in version 5.3.7.b.
When Wi-Fi usage is not required, disabling it mitigates the issue.
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
A remote attacker in Wi-Fi range is able to execute arbitrary code when
the Realtek (RTLWIFI) driver is being used on the affected host.
