openssl: openssl: Denial of Service via out-of-bounds write during TLS context switch

A flaw was found in openssl. When a server replaces its security context during an active Transport Layer Security TLS handshake, it fails to update the internal capacity tracking for cryptographic signature algorithms. A remote peer can exploit this issue by advertising specific signature...

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...
