CVE-2026-82474: Protection Mechanism Failure
Sudo through 1.9.17p2 fails to apply intercept policy checks to the execveat system call in ptrace-based intercept mode. Users permitted to run specific commands can execute denied programs by calling execveat directly or through fexecve, bypassing policy enforcement and logging...
Linux memfd_exec Evasion
Generate a Linux x64 ELF that decrypts a staged loader into memfdcreate and executes it with fexecve — fileless delivery effective against basic EDR. !/usr/bin/env python3 -- coding: utf-8 -- """ memfdcreate + fexecve fileless Linux loader. Builds an encrypted inner ELF loader, wraps it in an out...

CVE-2014-3880
CVE-2014-3880 affects the FreeBSD kernel: executing a new image can destroy the calling process’s virtual memory space before all threads terminate, dereferencing an invalid page table pointer and triggering a triple fault leading to a reboot. Affected: FreeBSD 8.4 (before p11), 9.1 (before p14),...
