CVE-2026-33845: gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

Severity: Critical

CVSS Score: 9.1

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
