A flaw was found in Netty's StompSubframeDecoder component. (CVE-2026-93494)
A vulnerability in Netty's StompSubframeDecoder component allows a remote attacker to cause a permanent memory leak by sending a specially crafted STOMP frame body without its terminating null byte. This memory leak can lead to a denial of service (DoS) due to uncontrolled memory consumption.
AI Analysis
Technical Summary
CVE-2026-93494 describes a flaw in the StompSubframeDecoder component of Netty where the decoder allocates a ByteBuf that is never released if it receives a STOMP frame body missing its terminating null byte. This results in a permanent memory leak that can accumulate over time, potentially causing a denial of service condition in applications using the affected STOMP codec.
Potential Impact
The vulnerability allows remote attackers to cause a denial of service by exhausting memory resources through repeated sending of malformed STOMP frames. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider implementing network-level protections to restrict or monitor malformed STOMP frames to mitigate potential exploitation.
