Background
The Linux Kernel is the core component of the Linux operating system, responsible for managing system resources and providing an interface for applications to interact with the hardware. It is a critical piece of software that is widely used across various devices and platforms. The vulnerability identified in this report relates to a data race issue in the TCP subsystem of the Linux Kernel.
Vulnerability Detail
The data race vulnerability in the Linux Kernel's TCP subsystem revolves around a race condition specifically related to the sysctl_tcp_probe_interval parameter. This parameter controls the interval at which TCP probes are sent. The data race occurs when multiple threads or processes attempt to modify this parameter concurrently, leading to unpredictable behavior and potential security risks. Although the impact and attack plausibility have not been proven, data races can result in various issues such as crashes, incorrect results, and even security vulnerabilities.
