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.

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.
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.

CVE-2022-0435 is classified as a high severity vulnerability due to its potential for remote denial of service via kernel panic.
To mitigate CVE-2022-0435, upgrade your kernel to versions 0:4.18.0-348.20.1.rt7.150.el8_5 or 0:4.18.0-348.20.1.el8_5 for Red Hat systems.
CVE-2022-0435 affects multiple versions of the Linux kernel, particularly those utilizing TIPC networking in Red Hat and Fedora distributions.
Exploitation of CVE-2022-0435 can result in a remote denial of service, which may crash systems utilizing the vulnerable TIPC module.
CVE-2022-0435 is a remote vulnerability, allowing attackers to potentially cause harm without requiring local access.
