CVE-2016-4557

This Metasploit module exploits CVE-2016-4557, a Linux BPF local privilege escalation vulnerability. It leverages BPF syscalls to manipulate file descriptors and achieve root privileges on vulnerable systems.

This exploit leverages a use-after-free vulnerability in the Linux kernel's eBPF subsystem (CVE-2016-4557) to achieve local privilege escalation. The flaw arises from a double fdput() call when handling invalid eBPF map file descriptors, allowing an attacker to manipulate file references and gain root access.

This Metasploit module exploits CVE-2016-4557, a use-after-free vulnerability in the Linux kernel's eBPF subsystem, to achieve local privilege escalation. It targets Linux kernel versions 4.4 to 4.5.5 by manipulating file descriptors and requires specific kernel configurations.
