CVE-2026-68316

The CVE affects the Linux kernel accel: ethosu component. Two issues in command stream validation lead to undercounted element sizes for 16/32/64-bit elements and, for NHWC format, missing element size in the calculation. The element-size bitfield differs between IFM/IFM2 (bits 2:3) and OFM (bits...
