Vulnerability from variot
The ThreadX-based firmware on Marvell Avastar Wi-Fi devices, models 88W8787, 88W8797, 88W8801, 88W8897, and 88W8997, allows remote attackers to execute arbitrary code or cause a denial of service (block pool overflow) via malformed Wi-Fi packets during identification of available Wi-Fi networks. Exploitation of the Wi-Fi device can lead to exploitation of the host application processor in some cases, but this depends on several factors including host OS hardening and the availability of DMA. plural Marvell Made Avastar wireless SoC The model includes Wi-Fi Multiple vulnerabilities exist including memory block pool overflow during network scans. ZeroNights 2018 Conference In Marvell Avastar SoC Several vulnerabilities were introduced and details about memory block pool overflow were announced. Wi-Fi An overflow condition occurs during a network scan, overwriting data in a specific memory block pool. Many devices automatically perform network scanning in the background, so this vulnerability can be exploited regardless of whether the target device is connected to a wireless network and without user intervention. There is a possibility.Wi-Fi Specially crafted by unauthenticated attackers within reach of Wi-Fi Using frames Marvell SoC Arbitrary code may be executed on systems with. Depending on the implementation method, it was attacked SoC Can be used to intercept network traffic and execute code on the host system. MarvellAvastar Wi-Fi is a WiFi chipset used in routers, computers and other devices. A security hole exists in the ThreadX-based firmware on MarvellAvastar Wi-Fi. Multiple Marvell SOCs are prone to arbitrary code-execution vulnerabilities. An attacker can leverage these issues to execute arbitrary code in the context of the affected system
