# CVE-2026-39047
## Summary
A buffer overflow vulnerability in the RAW Printing Service (JetDirect/AppSocket) of EPSON L14150 FL27PB allows a remote unauthenticated attacker to trigger memory corruption conditions via crafted network payloads sent to TCP port 9100.
## Affected Product
- EPSON L14150 FL27PB
## Affected Component
- RAW Printing Service
- JetDirect/AppSocket
- TCP/9100
## Attack Vector
Remote, unauthenticated network access via TCP port 9100.
## Impact
Successful exploitation may result in:
- denial of service (DoS)
- parser instability
- abnormal firmware behavior
- potential remote code execution
## Technical Details
The vulnerability exists in the handling of malformed RAW print job payloads processed by the embedded printing parser exposed over TCP/9100.
