Descriptions

In the Linux kernel, the following vulnerability has been resolved:

IB/qib: Protect from buffer overflow in struct qib_user_sdma_pkt fields

Overflowing either addrlimit or bytes_togo can allow userspace to trigger
a buffer overflow of kernel memory. Check for overflows in all the places
doing math on user controlled buffers.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: IB/qib: Protege contra el desbordamiento del búfer en los campos de struct qib_user_sdma_pkt. El desbordamiento de addrlimit o bytes_togo puede permitir que el espacio de usuario desencadene un desbordamiento del búfer de la memoria del kernel. Compruebe si hay desbordamientos en todos los lugares que realizan cálculos en búferes controlados por el usuario.
