CVE-2026-102759

NetX Secure TLS accepts an empty application-data record without verifying its message authentication code. In nxsecureverifymac, a decrypted application record whose length equals the negotiated MAC size is treated as valid and returns success after advancing the receive sequence number. The...

CVE-2026-102759

NetX Secure TLS is vulnerable to a flaw where it accepts empty application-data records without performing message authentication code (MAC) verification . Specifically, in the _nx_secure_verify_mac function, if a decrypted application record's length matches the negotiated MAC size, the system t...

CVE-2026-102758

The nxsecurex509asn1tlvblockparse function parses ASN.1 TLV tag-length-value blocks out of DER-encoded data. It is the primitive underneath all X.509 certificate parsing in NetX Secure, and therefore runs on certificates supplied by a remote peer during the TLS handshake. The function reads the...

CVE-2026-102758

The NetX Secure library contains a vulnerability in the _nx_secure_x509_asn1_tlv_block_parse() function, which handles ASN.1 TLV blocks during X.509 certificate parsing. The root cause is an out-of-bounds read because the function reads a one-byte ASN.1 tag from the buffer before verifying that t...

Name of the Vulnerable Software and Affected Versions NetX Secure affected versions not specified Description The software generates predictable cookies during the DTLS HelloVerifyRequest process. This predictability can be exploited to bypass the cookie-based mechanism intended to prevent Denial...

CVE-2026-102758: Buffer Over-read

The nxsecurex509asn1tlvblockparse function parses ASN.1 TLV tag-length-value blocks out of DER-encoded data. It is the primitive underneath all X.509 certificate parsing in NetX Secure, and therefore runs on certificates supplied by a remote peer during the TLS handshake. The function reads the...

CVE-2026-102728: Buffer Over-read

Two client-side TLS/DTLS handshake parsers in NetX Secure read fields from a server-supplied message before validating that the message is long enough to contain them. Both are bounded out-of-bounds reads on a remotely reachable path, both are reached from a TLS or DTLS client connecting to a...

Name of the Vulnerable Software and Affected Versions NetX Secure affected versions not specified Description Two client-side TLS/DTLS handshake parsers contain bounded out-of-bounds reads. This occurs when the parsers read fields from a server-supplied message before validating if the message is...

Name of the Vulnerable Software and Affected Versions NetX Secure affected versions not specified Description An issue exists in the nx secure x509 asn1 tlv block parse function, which is used to parse ASN.1 TLV tag-length-value blocks from DER-encoded data during X.509 certificate parsing in TLS...

CVE-2026-102759: Improper Validation of Integrity Check Value

NetX Secure TLS accepts an empty application-data record without verifying its message authentication code. In nxsecureverifymac, a decrypted application record whose length equals the negotiated MAC size is treated as valid and returns success after advancing the receive sequence number. The...

CVE-2026-102760: Use After Free

When NetX Secure is built with NXSECUREKEYCLEAR, every TLS record sent on an active session is wiped after it has been handed to TCP. By then the TCP layer owns the packet chain and may already have released it to the packet pool. The wipe therefore writes zeros into packets that are free or in u...
