CVE-2026-53206

Service interruption via unchecked firmware runtime bounds

Published Jun 25, 2026 · Updated Jun 25, 2026

Bounds validation failure in the ivpu driver in Linux Kernel 6.19 allows local users to interrupt service through a malformed firmware image. The ivpu_fw_parse function trusts header-derived runtime address and size values without confirming page alignment or that the runtime allocation can hold the image before allocating memory and copying it. Reachability requires affected Intel VPU hardware and a malformed image to reach the firmware loader; the documented consequence is limited to allocation or image-transfer failure and service interruption.
