"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-pci: fix a NULL pointer dereference in nvme_alloc_admin_tags\n\nIn nvme_alloc_admin_tags, the admin_q can be set to an error (typically\n-ENOMEM) if the blk_mq_init_queue call fails to set up the queue, which\nis checked immediately after the call. However, when we return the error\nmessage up the stack, to nvme_reset_work the error takes us to\nnvme_remove_dead_ctrl()\n nvme_dev_disable()\n nvme_suspend_queue(&dev->queues[0]).\n\nHere, we only check that the admin_q is non-NULL, rather than not\nan error or NULL, and begin quiescing a queue that never existed, leading\nto bad / NULL pointer dereference."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvme-pci: corrige una desreferencia de puntero NULL en nvme_alloc_admin_tags En nvme_alloc_admin_tags, admin_q se puede configurar en un error (normalmente -ENOMEM) si la llamada blk_mq_init_queue no puede configurar la cola, que se comprueba inmediatamente despu\u00e9s de la llamada. Sin embargo, cuando devolvemos el mensaje de error a la pila, a nvme_reset_work el error nos lleva a nvme_remove_dead_ctrl() nvme_dev_disable() nvme_suspend_queue(&dev->queues[0]). Aqu\u00ed, solo comprobamos que admin_q no sea NULL, en lugar de no ser un error o NULL, y comenzamos a inactivar una cola que nunca existi\u00f3, lo que lleva a una desreferencia de puntero NULL incorrecta."
