EUVD-2026-39261

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: reject DMA commands with uninitialized length cmdstateinit initializes the command state with memset0xff, leaving dma-len at U64MAX to signal missing setup. The only setter is NPUSETDMA0LEN; if userspace omits this...

PT-2026-52267

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description Arithmetic issues exist in the dma length function within the accel/ethosu component. The function calculates DMA region usage based on command stream values to update the region size...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An out-of-bounds write issue exists in the command stream parser of the Ethos-U NPU accelerator. The NPU SET IFM REGION operation incorrectly uses a 0x7f mask when extracting the region...

PT-2026-52265

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the accel/ethosu component where the driver does not implement the NPU OP RESIZE command, which is specific to U85. When a user submits this command via the DRM IOCTL...
