Background
The TIPC (Transparent Inter-Process Communication) is a protocol used for communication between processes in the Linux kernel. It provides reliable and ordered message delivery across a network. The vulnerability in TIPC affects the Linux Kernel, specifically versions 4.8 to 5.10.100. TIPC domain records received by the kernel are not properly validated for size, which can lead to potential security vulnerabilities.
Vulnerability Detail
The vulnerability arises from the lack of proper size validations for TIPC domain records received by the Linux Kernel. Attackers can exploit this vulnerability to trigger buffer overflows or other memory corruption issues, potentially leading to privilege escalation, denial of service, or arbitrary code execution. The impact and attack plausibility of this vulnerability have not been proven yet.
