Linux Distros Unpatched Vulnerability : CVE-2026-93304

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A DTLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client...

DEBIAN-CVE-2026-93304

A DTLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client installs read keys derived from a known deterministic key and checks the server's Finished against that same key. An out-of-order...

CVE-2026-93304 (D)TLS 1.2 client accepts early ChangeCipherSpec before ClientKeyExchange

A DTLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client installs read keys derived from a known deterministic key and checks the server's Finished against that same key. An out-of-order...

CVE-2026-93304

A (D)TLS 1.2 client is vulnerable to an out-of-order ChangeCipherSpec message being accepted before the ClientKeyExchange is sent. Because the master secret is not yet derived, the client installs read keys from a known deterministic key, allowing a man-in-the-middle attacker to complete the hand...
