      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info\n\nThe MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and the\nroutine unconditionally frees submitted mailbox commands regardless of\nreturn status.  The issue is that for MBX_TIMEOUT cases, when firmware\nreturns SFP information at a later time, that same mailbox memory region\nreferences previously freed memory in its cmpl routine.\n\nFix by adding checks for the MBX_TIMEOUT return code.  During mailbox\nresource cleanup, check the mbox flag to make sure that the wait did not\ntimeout.  If the MBOX_WAKE flag is not set, then do not free the resources\nbecause it will be freed when firmware completes the mailbox at a later\ntime in its cmpl routine.\n\nAlso, increase the timeout from 30 to 60 seconds to accommodate boot\nscripts requiring longer timeouts."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: lpfc: Controlar los tiempos de espera del buzón en lpfc_get_sfp_info El código de retorno MBX_TIMEOUT no se maneja en lpfc_get_sfp_info y la rutina libera incondicionalmente los comandos de buzón enviados independientemente del estado de retorno. El problema es que para los casos de MBX_TIMEOUT, cuando el firmware devuelve información SFP en un momento posterior, esa misma región de memoria del buzón hace referencia a la memoria liberada previamente en su rutina cmpl. Se soluciona agregando comprobaciones para el código de retorno MBX_TIMEOUT. Durante la limpieza de recursos del buzón, verifique el indicador mbox para asegurarse de que la espera no haya expirado. Si el indicador MBOX_WAKE no está configurado, no libere los recursos porque se liberarán cuando el firmware complete el buzón en un momento posterior en su rutina cmpl. Además, aumente el tiempo de espera de 30 a 60 segundos para dar cabida a los scripts de arranque que requieren tiempos de espera más largos."
