CVE-2026-9002
Full vulnerability record from the local CVENow database.
Description
IBM WebSphere Extreme Scale 8.6.1.0 through 8.6.1.6 could allow an adjacent attacker to cause a denial of service due to improper validation in the XDF decoder. The application processes deeply nested Protocol Buffers messages and attacker-controlled length prefixes without sufficient bounds checking, which may allow an attacker on the same network to trigger a StackOverflowError or OutOfMemoryError, resulting in a crash of the WebSphere Application Server JVM.

La aplicación procesa mensajes de Protocol Buffers profundamente anidados y prefijos de longitud controlados por el atacante sin una comprobación de límites suficiente, lo que podría permitir a un atacante en la misma red activar un StackOverflowError o OutOfMemoryError, resultando en un fallo de la JVM del servidor de aplicaciones WebSphere."
