Summary
[none]
Details

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Treat remaining == 0 as error in findandmapuserpages() Currently, if findandmapuserpages() takes a DMA xfer request from the user with a length field set to 0, or in a rare case, the host receives QAICTRANSDMAXFERCONT from the device where resources->xferreddmasize is equal to the requested transaction size, the function will return 0 before allocating an sgt or setting the fields of the dmaxfer struct. In that case, encodeaddrsizepairs() will try to access the sgt which will lead to a general protection fault. Return an EINVAL in case the user provides a zero-sized ALP, or the device requests continuation after all of the bytes have been transferred.
