CVE-2026-33845 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:6.
NVD Description
Note: Versions mentioned in the description apply only to the upstream gnutls-devel package and not the gnutls-devel package as distributed by RHEL.
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.
