CVE-2026-71987Network attack vector

Unauthenticated root command execution via alg function

Published Aug 8, 2026 · Updated Aug 8, 2026

OS command injection in MSI RadiX AXE6600 firmware 781521 allows remote attackers to execute arbitrary commands as root through the alg function. The published advisory identifies the alg function as the vulnerable locus but does not disclose the affected input or its unsafe command-building operation. Unauthenticated network access and no user interaction are sufficient; successful exploitation gives root control of the router.
