CVE-2026-43184

In the Linux kernel, the following vulnerability has been resolved: rnbd-srv: Zero the rsp buffer before using it Before using the data buffer to send back the response message, zero it completely. This prevents any stray bytes to be picked up by the client side when there the message is exchanged between different protocol versions.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: rnbd-srv: Poner a cero el búfer rsp antes de usarlo Antes de usar el búfer de datos para devolver el mensaje de respuesta, póngalo a cero completamente. Esto evita que cualquier byte residual sea capturado por el cliente cuando el mensaje se intercambia entre diferentes versiones de protocolo.
