CVE-2026-98143

A flaw was found in the Linux kernel's Arm Ethos-U neural processing unit NPU accelerator driver. The command stream parser incorrectly interprets hardware rounding mode fields as storage mode parameters on certain device models. A local user can exploit this vulnerability by submitting specific...

PT-2026-98805

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ethosu accelerator driver where the command stream parser incorrectly interprets bits 15:14 of NPU SET IFM,OFM PRECISION as an activation storage mode on U65...

CVE-2026-53172

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix IFM region index out-of-bounds in command stream parser NPUSETIFMREGION extracts the region index with param & 0x7f, giving a maximum value of 127. However regionsize and outputregion in struct...

CVE-2026-53172

The CVE-2026-53172 issue in the Linux kernel’s accel/ethosu component is a local-privilege/heap corruption flaw caused by an incorrect mask (0x7f) when processing NPU_SET_IFM_REGION. This allows a userspace caller to supply a region index > 7, writing up to 1016 bytes past the start of region_...
