Background
The rtl8712 driver is part of the Linux Kernel and is responsible for managing the Realtek RTL8712U Wireless LAN 802.11n USB 2.0 network adapter. This driver enables communication between the adapter and the operating system, allowing users to connect to wireless networks. However, a vulnerability has been discovered in the driver that could lead to a memory leak.
Vulnerability Detail
The vulnerability exists in the r871xu_drv_init() function of the rtl8712 driver. This function is called during the initialization of the driver and is responsible for allocating and initializing resources. However, there is a potential memory leak in this function, which means that memory allocated during initialization may not be properly freed, leading to a gradual depletion of available memory. This could result in system instability, crashes, or even denial of service if the memory leak is severe enough.
How To Fix
