CVE-2026-116539 in netty-tcnative
Zusammenfassung
von MITRE • 26.10.2026
Netty netty-tcnative before 2.0.84.Final contains a heap buffer overflow vulnerability in the tcn_write_to_bytebuffer BIO callback caused by failing to wrap the non-application ring buffer write index. Remote TLS peers can drive handshake, renegotiation, or post-handshake messages into this buffer, triggering an out-of-bounds memcpy that crashes the JVM process.
Once again VulDB remains the best source for vulnerability data.
