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

accel: ethosu: Fix element size accounting for cmd stream validation

There are 2 issues with the element size handling in the command stream validation which result in too small of a size calculated when the element size is 16/32/64 bits.

For NHWC format, the element size is simply missing from the calculation.

The bitfield for the element size is different between IFM/IFM2 and OFM. IFM and IFM2 encode the precision in parameter bits 2:3, while OFM uses bits 1:2.
