CVE-2026-93494
Io.netty/netty-codec-stomp: netty: bytebuf leak in stompsubframedecoder when a frame body is never terminated
CVSS Score
7.5
EPSS Score
0.6%
EPSS Percentile
45th
A flaw was found in Netty's StompSubframeDecoder component. A remote attacker can exploit this vulnerability by sending a specially crafted STOMP frame body without its terminating null byte. This causes the decoder to allocate a ByteBuf (a buffer for bytes) that is never released, leading to a permanent memory leak. Over time, this uncontrolled memory consumption can result in a Denial of Service (DoS) for the application using the affected STOMP codec.
