CVE-2026-68316

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the command stream validation of the ethosu accelerator where element size is incorrectly calculated when it is 16, 32, or 64 bits. This occurs because the element size is omitted from the calculation for the NHWC (channels-last) format. Additionally, there is a discrepancy in how the element size bitfield is handled between IFM/IFM2, which encode precision in parameter bits 2:3, and OFM, which uses bits 1:2.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
