bpfjailer

BpfJailer eBPF based Mandatory Access Control for Linux. This project is a full rewrite of the closed source BpfJailer and is completely experimental. It leverages newer features like bpf arena that were not available when the internal BpfJailer was written. Issues are expected and are not eligib...

block-copyfail

block-copyfail Proof of concept runtime mitigation for CVE-2026-31431 "Copy Fail" — a Linux kernel privilege escalation via the authencesn cryptographic template in algifaead. Unlike module blacklisting, this requires no reboot. A BPF LSM program hooks socketbind and blocks all AFALG AEAD binds —...

owLSM

🛡️ owLSM aspires to become the gold standard for prevention and detection for Linux 🛡️ owLSM is an eBPF LSM agent that implements a stateful Sigma rules engine focused on prevention. What is the project: owLSM focuses on three main things: 1 Prevention capabilities using a Sigma Rules Engine...

kprotect

🛡️ kprotect Overview kprotect is a kernel-level security engine designed to protect your sensitive data from supply-chain attacks like malicious Python or Node.js libraries. It stands as an independent security layer for the most sensitive files. eBPF-LSM Enforcement : Intercepts file access at th...

agent

Bomfather Agent Bomfather Agent is an eBPF-based agent that runs in the kernel space to block actions based on a policy. We built this agent to solve the problems we had with existing solutions. 1. They were too complex to set up and use. 2. They were too slow and inefficient. 3. And even if they...

copy-fail-blocker

copy-fail-blocker BPF-LSM mitigation for CVE-2026-31431 "Copy Fail" and the RxRPC variant of Dirty Frag, and for similar privilege-escalation vulnerabilities that depend on userspace access to a kernel-side in-place crypto path reachable via the AFALG or AFRXRPC socket families. A small DaemonSet...

bombini

Bombini: eBPF-based Security Monitoring and Sandboxing Agent Bombini is an eBPF-based security agent written entirely in Rust using the Aya library and built on LSM Linux Security Module BPF hooks. At its core, Bombini employs modular components called Detectors, each responsible for monitoring a...

cplt

cplt Kernel-enforced sandbox for AI coding agents. cplt wraps GitHub Copilot CLI, OpenCode, Gemini CLI, Antigravity CLI, Pi, Claude Code, goose, DeepSeek Harness, or any shell, so the agent can write code but cannot steal credentials, push to main, merge PRs, or exfiltrate secrets. macOS : Apple...

deny-af-alg-bpf

deny-af-alg-bpf Description BPF LSM program that blocks AFALG Linux kernel crypto API socket creation and logs all attempts via a ring buffer to userspace. What it does Attaches to the lsm/socketcreate hook Denies any socketAFALG, ... call with -EPERM Emits structured events pid, comm to a BPF ri...

lockc

lockc is open source sofware for providing MAC Mandatory Access Control type of security audit for container workloads. The main reason why lockc exists is that containers do not contain. Containers are not as secure and isolated as VMs. By default, they expose a lot of information about host OS...

lsm_bpf_check_argc0

Check ARGC0 LSM BPF Simple LSM BPF program to prevent program executions with argc == 0, e.g. pwnkit CVE-2021-4034. It does nothing more than a simple check that all exec system calls are called with argc = 1. The check is based on Ariadne Conill's patch. How to build On Ubuntu $ sudo apt-get...

CVE-2026-93173

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF and Linux Security Module LSM subsystems. This vulnerability occurs when a sleepable LSM program is incorrectly handled during the freeing of non-sleepable BPF programs. An attacker could potentially trigger a system crash, leading...
