# CVE-2026-33846: gnutls28: A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS CVE-2026-33846 is fixed in 21 products on 1 platform, first by gnutls-bin 3.5.18-1ubuntu1.6+esm3, released May 4, 2026. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2026-33846 - Priority: High - CVSS: 8.2 (high) - EPSS: 0.0126 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: May 4, 2026 ## Description A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption. ## Where it's fixed | Platform |
