CVE-2026-92843

A missing bounds check in the TLS 1.3 Certificate-message parser of NetX Secure allows a malicious TLS 1.3 server to trigger an unsigned-integer underflow . This results in a heap out-of-bounds read in any peer processing a remote Certificate message. The vulnerability is reachable pre-authentica...

CVE-2026-92843 Out-of-bounds Read via the TLS 1.3 Certificate extensions_length in NetX Secure

A missing bounds check in the TLS 1.3 Certificate-message parser of NetX Secure lets a malicious TLS 1.3 server trigger an unsigned-integer underflow and a subsequent heap out-of-bounds read in any peer that processes a remote Certificate message. It is reachable pre-authentication, during the...

EUVD-2026-105133

The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to 0xFFFFFFFF, which makes the bounds check that follows...

CVE-2026-92853

The NetX Secure TLS 1.3 Certificate-message parser is vulnerable to an out-of-bounds read due to an integer underflow . The parser decrements the message length to skip a context byte without verifying if a byte exists; a zero-length Certificate message causes the unsigned length to wrap to 0xFFF...

CVE-2026-92853 Out-of-bounds Read via a Zero-length TLS 1.3 Certificate Message in NetX Secure

The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to 0xFFFFFFFF, which makes the bounds check that follows...

CVE-2026-101302

TLS 1.3 embeds the actual record type as the last non-zero byte of the decrypted payload, optionally followed by zero padding. The code which searches for the inner record type had an off-by-one bug which could be triggered by an invalid frame, leading to an underflow followed by an unconditional...

CVE-2026-73252 Mongoose: Unauthenticated remote heap out-of-bounds read in built-in TLS: off-by-one length check in mg_tls_recv_record() underflows recv_len to SIZE_MAX

Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TLS stack selected by MGTLSBUILTIN in src/tlsbuiltin.c accepts a TLS 1.3 record whose decrypted size is exactly the 16-byte authentication tag with no plaintext or ContentType byte. In mgtlsrecvrecord, the msgsz...

CVE-2026-103415

When a TLS 1.3 client processes a HelloRetryRequest, it copies the server's cookie into its second ClientHello without checking that the cookie fits in the outgoing packet. Both the length and the contents of that cookie come from the peer, and the write happens before certificate authentication...
