Background
The tipc package is a part of the Linux Kernel ecosystem. It provides the Transparent Inter-Process Communication (TIPC) protocol, which enables communication between processes running on different nodes in a cluster. TIPC is primarily used for high-availability and fault-tolerant systems. However, a vulnerability has been discovered in the tipc package that affects the timer functionality.
Vulnerability Detail
The vulnerability in the tipc package involves a timer that expires after an interval of 100ms. This issue can potentially lead to timing-related attacks and disrupt the normal operation of the system. An attacker could exploit this vulnerability to manipulate the timing behavior of the system, potentially causing denial-of-service (DoS) or other malicious activities. The vulnerability was introduced in version v4.20 of the Linux Kernel and has been fixed in version v5.16.19.
