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.

No CVSS v4.0

No CVSS v3.1
