UBUNTU-CVE-2026-5680

A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer method using exponential doubling,...

CVE-2026-5680

Undertow (specifically the Undertow-core component) is vulnerable to a Denial of Service (DoS) attack exploitable over the network without authentication. A remote attacker can send specially crafted WebSocket messages with the permessage-deflate extension negotiated, triggering excessive memory ...

CVE-2026-5680 Undertow-core: undertow: denial of service via websocket permessage-deflate processing

A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer method using exponential doubling,...

Uncontrolled Resource Consumption (Denial Of Service)

Netty is vulnerable to Uncontrolled Resource Consumption Denial of Service. The vulnerability is due to improper handling of the HAProxy protocol version byte in the HAProxyMessageDecoder, where a signed Java byte is widened to an int without masking, causing a crafted 0xFF version byte to be...

CVE-2026-55851

A flaw was found in Netty's codec-haproxy module. A remote attacker could exploit a vulnerability in the HAProxyMessageDecoder by sending a specially crafted PROXY protocol v2 message. This leads to unbounded buffer accumulation, causing a denial of service DoS due to memory exhaustion...
