Descriptions

In the Linux kernel, the following vulnerability has been resolved: comedi: vmk80xx: fix bulk-buffer overflow The driver is using endpoint-sized buffers but must not assume that the
tx and rx buffers are of equal size or a malicious device could overflow
the slab-allocated receive buffer when doing bulk transfers.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: comedi: vmk80xx: corrige el desbordamiento masivo del búfer El controlador utiliza búferes del tamaño de un endpoint, pero no debe asumir que los búferes tx y rx son del mismo tamaño o un dispositivo malicioso podría desbordar el búfer de recepción asignado por losa al realizar transferencias masivas.
