Background
The Linux Kernel is the core component of the Linux operating system. It provides essential functionality and acts as an interface between the hardware and software layers. The Bluetooth subsystem in the Linux Kernel enables communication with Bluetooth devices, allowing for wireless connectivity. However, a vulnerability has been identified in the Bluetooth implementation that can lead to memory leaks.
Vulnerability Detail
The vulnerability in the Bluetooth implementation of the Linux Kernel is related to memory leaks. Specifically, the issue arises from the improper use of memory allocation and deallocation functions. When certain Bluetooth operations are performed, memory is allocated but not properly freed, resulting in memory leaks. This can lead to a depletion of available memory resources, potentially causing system instability or denial of service conditions. The vulnerability has been assigned the ID GSD-2022-1001718.
