## Summary Fix high severity security issue in `boards/mips/pic32mx/pic32mx7mmb/src/pic32_touchscreen.c`. ## Vulnerability | Field | Value | |-------|-------| | **ID** | V-004 | | **Severity** | HIGH | | **Scanner** | multi_agent_ai | | **Rule** | `V-004` | | **File** | `boards/mips/pic32mx/pic32mx7mmb/src/pic32_touchscreen.c:1358` | | **Assessment** | Likely exploitable | **Description**: Memory allocation failures are logged but not properly handled, potentially leading to NULL pointer dereferences if execution continues with uninitialized pointers. ## Evidence **Exploitation scenario**: System under memory pressure causes kmm_malloc() to fail, leading to crashes when NULL pointers are dereferenced in driver code. **Scanner confirmation**: multi_agent_ai rule `V-004` flagged this pattern. **Production code**: This file is in the production codebase, not test-only code. ## Threat Model Context This is a local CLI tool - exploitation requires the attacker to control command-line arguments or input files. ## Changes - `boards/mips/pic32mx/pic32mx7mmb/src/pic32_touchscreen.c` ## Verification - [x] Build passes - [x] Scanner re-scan confirms fix - [x] LLM code review passed --- *Automated security fix by [OrbisAI Security](https://orbisappsec.com)* -- This is an automated message from the Apache Git Service.
