CVE-2013-1979 kernel: net: incorrect SCM_CREDENTIALS passing
Commit 257b5358b32f ("scm: Capture the full credentials of the scm sender") changed the credentials passing code to pass in the effective uid/gid instead of the real uid/gid.
Obviously this doesn't matter most of the time (since normally they are the same), but it results in differences for suid binaries when the wrong uid/gid ends up being used.
An unprivileged local user could use this flaw to elevate their privileges.

## Abstract
We introduce , a novel technique for automatically learning system
call filtering policies for containerized microservices applications. At
run-time, automatically learns which system calls a program should
be allowed to invoke, while rejecting attempts to call spurious system calls.
Further, addresses many of the shortcomings of state-of-the-art
static analysis-based techniques, such as the ability to generate tight filters
for programs written in interpreted languages such as PHP, Python, and
JavaScript. has a simple and rob
