CVE-2026-11703 Missing SNI/ALPN binding on stateful (session-ID) TLS session resumption
Missing SNI/ALPN binding on stateful session-ID resumption, which previously skipped the binding check performed for ticket-based resumption. A cached session could be resumed under a different SNI/ALPN than originally negotiated and, where client-authentication policy differs across virtual host...
CVE-2026-7531
Use-after-free in PQC hybrid key-share handling. This is an incomplete-fix follow-up to CVE-2026-5460 released in 5.9.1: a malicious TLS 1.3 server sending a truncated PQC hybrid KeyShare can still trigger the error cleanup path to operate on freed memory...
CVE-2026-55958
Out-of-bounds write in the Renesas TSIP TLS 1.3 transcript buffer. In tsipStoreMessage the capacity check guarding the fixed message bag MSGBAGSIZE sets an error code but fails to return, so execution falls through to an XMEMCPY that writes past the end of the buffer once the accumulated TLS 1.3...

CVE-2026-6679 DTLS 1.3 ACK serialization heap buffer overflow via integer truncation
A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...

netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake
A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...
