CVE-2026-68316
High
Description
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.
