Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-46340)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource consumption in SCTP message reassembly in netty-transport-sctp when processing non-complete SCTP message fragments. A remote attacker can send a sequence of tiny fragmented DATA chunks that never set the complete flag to cause a denial of service.

Each stream identifier maintains its own accumulator entry, and there is no limit on fragment depth, total buffered bytes, or the number of stream identifiers tracked.
