UnverifiedThe vulnerability was identified during a code review of the TCP protocol stack's state-transition logic, rather than discovered by chance through routine fuzz testing.71% similarUnverifiedCVE-2026-98432 is a use-after-free vulnerability in the Linux kernel TCP protocol stack.66% similarVerifiedWhen UDP is completely blocked by a firewall, Tailscale ensures connectivity through DERP (Designated Encrypted Relay for Packets) relay servers, and end-to-end encryption prevents the relay servers from decrypting data content.66% similarUnverifiedcroc relies on a relay server to coordinate connections, attempts to establish a direct peer-to-peer connection via TCP hole punching, and if direct connection fails, relays the transfer through the relay server while maintaining end-to-end encryption.66% similar
