kernel: File descriptors passed over unix sockets are not properly accounted

It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system...

USN-2932-1: Linux kernel (Vivid HWE) vulnerabilities

Ben Hawkes discovered that the Linux netfilter implementation did not correctly perform validation when handling IPTSOSETREPLACE events. A local unprivileged attacker could use this to cause a denial of service system crash or possibly execute arbitrary code with administrative privileges...

DEBIAN-CVE-2013-4312

The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service memory consumption by sending each descriptor over a UNIX socket before closing it, related to net/unix/afunix.c and net/unix/garbage.c...
