Background
The Kernel is a fundamental component of the Linux operating system that manages system resources and facilitates communication between hardware and software. It provides essential functionalities for the proper functioning of the system. The zr364xx driver is responsible for supporting certain webcams that use the ZR364XX chip. This vulnerability specifically affects the zr364xx_start_readpipe function in the media subsystem of the Kernel.
Vulnerability Detail
The zr364xx_start_readpipe function in the zr364xx driver in the Kernel suffers from a memory leak vulnerability. This vulnerability allows an attacker to cause a memory leak by repeatedly invoking the zr364xx_start_readpipe function without properly releasing the allocated memory. If exploited, this vulnerability can lead to a depletion of system memory resources, potentially resulting in system instability or denial of service.
