Background
The rtl8712 driver is a component of the Linux Kernel, which is responsible for managing the Realtek RTL8712U Wireless LAN 802.11n USB 2.0 network adapter. This driver enables communication between the operating system and the wireless adapter, 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 memory resources. However, due to a coding error, there is a potential memory leak in this function. If the memory allocation fails, the function does not properly release the previously allocated memory, leading to a memory leak. This vulnerability could be exploited by an attacker to exhaust system memory, potentially causing a denial-of-service condition or other unexpected behavior.
How To Fix
