"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: xhci: Check for xhci->interrupters being allocated in xhci_mem_clearup()\n\nIf xhci_mem_init() fails, it calls into xhci_mem_cleanup() to mop\nup the damage. If it fails early enough, before xhci->interrupters\nis allocated but after xhci->max_interrupters has been set, which\nhappens in most (all?) cases, things get uglier, as xhci_mem_cleanup()\nunconditionally derefences xhci->interrupters. With prejudice.\n\nGate the interrupt freeing loop with a check on xhci->interrupters\nbeing non-NULL.\n\nFound while debugging a DMA allocation issue that led the XHCI driver\non this exact path."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: xhci: Comprueba que xhci->interrupters se asignen en xhci_mem_clearup() Si xhci_mem_init() falla, llama a xhci_mem_cleanup() para limpiar el da\u00f1o. Si falla lo suficientemente pronto, antes de que se asigne xhci->interrupters pero despu\u00e9s de que se haya establecido xhci->max_interrupters, lo que sucede en la mayor\u00eda (\u00bftodos?) de los casos, las cosas se ponen peor, ya que xhci_mem_cleanup() desreferencia incondicionalmente a xhci->interrupters. Con prejuicio. Bloquea el bucle de liberaci\u00f3n de interrupciones con una comprobaci\u00f3n de que xhci->interrupters no sea NULL. Se encontr\u00f3 mientras se depuraba un problema de asignaci\u00f3n de DMA que llev\u00f3 al controlador XHCI por este camino exacto."
