Worked on the Samsung/TizenRT repository to enhance security and maintainability in embedded Wi-Fi firmware using C programming and static analysis. Focused on consolidating multiple security improvements into a single bug fix, including replacing the PRNG entropy source with the BK7239 TRNG for mbedTLS hardware seeding and removing hardcoded demo keys from production sources. Addressed vulnerabilities such as CVE-2026-34871 and CVE-2026-25835 by eliminating credential exposure and strengthening cryptographic routines. Applied comprehensive static analysis to resolve NULL dereference, buffer overflow, and unreachable code issues, improving code health and aligning code paths with security best practices for future audits.
