CVE-2022-0435

First published: Mon Jan 31 2022(Updated: )

A remote stack overflow in the TIPC networking module. With FORTIFY_SOURCE's stricter memcpy() bounds checking, this can be exploited to cause remote DOS via kernel panic on systems using TIPC. Prior to these bounds checks, and with a canary leak (or no CONFIG_STACKPROTECTOR), this can be exploited for RCE.

Remedy

The TIPC module will NOT be automatically loaded. When required, administrative action is needed to explicitly load this module. Loading the module can be prevented with the following instructions: # echo "install tipc /bin/true" >> /etc/modprobe.d/disable-tipc.conf The system will need to be restarted if the tipc module is loaded. In most circumstances, the TIPC kernel module will be unable to be unloaded while any network interfaces are active and the protocol is in use. If the system requires this module to work correctly, this mitigation may not be suitable.

Remedy

Remedy

Ensure the tipc module is not loaded; unlike many other network protocols in the Linux kernel, the tipc module cannot be auto-loaded by an unprivileged user.
