A flaw was found in lwIP (Lightweight IP), a widely used open-source TCP/IP stack. This double free vulnerability allows an adjacent network attacker to potentially execute arbitrary code, corrupt memory, or cause a denial of service (DoS) on the affected system. The most severe impact is the possibility of arbitrary code execution, which could lead to full system compromise.
