CVE-2010-3880
First published: Tue Nov 09 2010(Updated: )
Description of problem: INET-DIAG is inconsistent about how it looks up the bytecode contained in a netlink message, making it possible for a user to cause the kernel to execute unaudited INET-DIAG bytecode. This can be abused to make the kernel enter an infinite loop, and possibly other consequences.
