CVE-2026-68316

Name	CVE-2026-68316
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.
Source	CVE (at NVD; CERT, ENISA, LWN, oss-sec, fulldisc, Debian ELTS, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
