Descriptions

In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value.

En el kernel de Linux versiones hasta 5.15.2, la función hw_atl_utils_fw_rpc_wait en el archivo drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c permite a un atacante (que puede introducir un dispositivo diseñado) desencadenar una escritura fuera de límites por medio de un valor de longitud diseñado

An out-of-bounds write flaw was found in the Linux kernel’s Aquantia AQtion Ethernet card Atlantic driver in the way the ethernet card provides malicious input to the driver. This flaw allows a local user to emulate the networking device and crash the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
