Last modified

CVE-2013-4270 is a vulnerability of currently unknown severity. The net_ctl_permissions function in net/sysctl_net.c in the Linux kernel before 3.11.5 does not properly determine uid and gid values, which allows local users to bypass intended /proc/sys/net restrictions via a crafted application.. EPSS estimates a 0.55% chance of exploitation in the next 30 days.
