CVE-2024-1151: Kernel: stack overflow problem in open vswitch kernel module leading to dos

First published: Thu Feb 01 2024(Updated: )

A flaw in the Linux Kernel found in the Open vSwitch Kernel module. The Netlink copy code in the ovs kernel module attempts to make an in-kernel copy of the actions required. That means that when recursive operations, like sample(), clone(), dec_ttl(), etc include additional actions, the code pushes a new stack frame and recursively calls into the code block. Unfortunately, OVS module doesn't validate the stack depth, and will push too many frames causing a stack overflow which can lead to crash.
