Critical Linux Kernel Bug Allows Remote Takeover | Exploitation & Update

The bug (CVE-2021-43267) capturing the TIPC message type enabling Linux hubs to send cryptographic keys to one another. 

The transparent Inter-Process Communication (TIPC) module of the Linux kernel is under hit that could permit local security threats and remote code execution, prompting full framework compromise. 

TIPC helps connect nodes within a Linux cluster.  It’s a P2P protocol that enables several types of messages that can be used for different purposes. Referring to SentinelOne’s SentinelLabs, the Linux bug in question (CVE-2021-43267) mainly comes in a specific type of message that enables nodes to share cryptographic keys with each other. When received, keys can decrypt any other communications from the other node.

Patching the Linux Kernel

The bug has a big effect on some Linux kernel versions. While the TIPC module contains all main Linux distributions, by default, it is never “on” nor needs it to be enabled for an implementation to be vulnerable to attack. Affected Linux users must apply just-released patch to protect themselves. It will add appropriate size-verification checks to the whole process.
