# CVE-2026-46333
Research and educational repository for **CVE-2026-46333**, focused on reproducible analysis and a safe test PoC workflow.
## 1) CVE-2026-46333
This project documents the vulnerability behavior, test setup, and validation approach so researchers and defenders can reproduce findings responsibly.
## 2) Safe Test PoC
This repository is intended for **authorized, local, and controlled testing only**.
- Use only on systems you own or have explicit permission to test.
- Do not run against production systems.
- Keep tests isolated (VM/container/lab host).
- Capture and share only non-sensitive outputs.
Safe PoC notes are in [docs/SAFE_TEST_POC.md](docs/SAFE_TEST_POC.md).
## 3) About Project
Project background, goals, and roadmap are in [docs/ABOUT.md](docs/ABOUT.md).
## Quick Start
```bash
go mod tidy
go build -o poc-test .
./poc-test [arg1 arg2 ...] [optional_file_to_capture]
```
Note: runtime execution is Linux-only because the PoC uses `pidfd_*` syscalls.
On non-Linux hosts, running `./poc-test` intentionally exits with:
`this PoC is Linux-only at runtime. Build with GOOS=linux to generate a Linux executable`.
## Cross-Platform Build (Target: Linux)
You can build a Linux executable from macOS, Linux, or Windows using Go cross-compilation:
```bash
# Linux amd64 binary
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -trimpath -ldflags "-s -w" -o bin/poc-test-linux-amd64 .
# Linux arm64 binary
CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -trimpath -ldflags "-s -w" -o bin/poc-test-linux-arm64 .
```
These commands produce static ELF binaries (no shared libc dependency).
## Prebuilt Binaries In Repo
This repository includes:
- `bin/poc-test-linux-amd64`
- `bin/poc-test-linux-arm64`
Direct use on Linux (authorized test environments only):
```bash
chmod +x bin/poc-test-linux-amd64
./bin/poc-test-linux-amd64 [arg1 arg2 ...] [optional_file_to_capture]
```
## Verified Command Results
Validated in this repo on May 17, 2026:
- `go mod tidy`: success
- `go build -o poc-test .`: success
- `./poc-test` on non-Linux host: expected Linux-only exit message
- `CGO_ENABLED=0 GOOS=linux GOARCH=amd64 ...`: success
- `CGO_ENABLED=0 GOOS=linux GOARCH=arm64 ...`: success
