Descriptions
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service.
Se encontró una falla en el controlador NVMe del kernel de Linux. Este problema puede permitir que un actor malicioso no autenticado envíe un conjunto de paquetes TCP manipulados cuando usa NVMe sobre TCP, lo que lleva al controlador NVMe a una desreferencia del puntero NULL en el controlador NVMe, lo que provoca pánico en el kernel y una denegación de servicio.
