Linux Kernel Vulnerability in Ethosu Hardware by Vendor

CVE-2026-98143

What is CVE-2026-98143?

A flaw in the Linux kernel's Ethosu driver leads to improper handling of command stream settings, particularly concerning the U65 hardware's precision configuration. The driver erroneously reads bits meant for rounding modes as storage modes, resulting in failed command stream operations when natural rounding is requested. This issue has resulted in multiple failures in the Teflon test suite on i.MX93, highlighting the need for careful inspection and correction of command stream handling to ensure proper functionality across various operations.
