CVE-2026-33845
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.
View on NVDAnalysis
GnuTLS is vulnerable to a remote integer underflow during DTLS handshake parsing, which can lead to information disclosure or a denial of service. Since GnuTLS is a core component of RHEL, OpenShift, and many Linux-based applications, users should update their packages immediately to secure their encrypted communications.
