Background
The Kernel package is a fundamental component of the Linux operating system. It provides the core functionality and interfaces for the system's hardware and software components. The IPv6 socket control block is a data structure used by the Kernel to manage IPv6 network connections. It contains information about the socket, such as the source and destination IP addresses, ports, and other parameters. The vulnerability in the IPv6 socket control block allows for potential security risks that could be exploited by attackers.
Vulnerability Detail
The vulnerability in the IPv6 socket control block arises from an issue with the 'iif' (input interface) parameter. This parameter is used to specify the input interface for incoming packets. However, due to a coding error, the 'iif' parameter is not properly handled, leading to potential security vulnerabilities. The impact and attack plausibility of this vulnerability have not been proven yet. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.10.85 by commit 666521b3852d2b2f52d570f9122b1e4b50d96831. The vulnerability was introduced in version v5.0 by commit ef489749aae508e6f17886775c075f12ff919fb1.
