"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncifs: fix underflow in parse_server_interfaces()\n\nIn this loop, we step through the buffer and after each item we check\nif the size_left is greater than the minimum size we need. However,\nthe problem is that \"bytes_left\" is type ssize_t while sizeof() is type\nsize_t. That means that because of type promotion, the comparison is\ndone as an unsigned and if we have negative bytes left the loop\ncontinues instead of ending."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cifs: corrige el desbordamiento insuficiente en parse_server_interfaces() En este bucle, recorremos el b\u00fafer y despu\u00e9s de cada elemento comprobamos si size_left es mayor que el tama\u00f1o m\u00ednimo que necesitamos. Sin embargo, el problema es que \"bytes_left\" es del tipo ssize_t mientras que sizeof() es del tipo size_t. Eso significa que debido a la promoci\u00f3n de tipo, la comparaci\u00f3n se realiza sin firmar y si nos quedan bytes negativos, el ciclo contin\u00faa en lugar de finalizar."
