CVE-2026-43310 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC For the i.MX8MQ platform, there is a hardware limitation: the g1 VPU and g2 VPU cannot decode simultaneously; otherwise, it will cause below bus error and produce corrupted pictures, even potentially lead to system hang. [ 110.527986] hantro-vpu 38310000.video-codec: frame decode timed out. [ 110.583517] hantro-vpu 38310000.video-codec: bus error detected. Therefore, it is necessary to ensure that g1 and g2 operate alternately. This allows for successful multi-instance decoding of H.264 and HEVC. To achieve this, g1 and g2 share the same v4l2_m2m_dev, and then the v4l2_m2m_dev can handle the scheduling.
A vulnerability in the Linux kernel's handling of video decoding on the i.MX8MQ platform has been addressed. The issue arose because the G1 and G2 video processing units (VPUs) could not decode simultaneously due to a hardware limitation. This conflict led to bus errors, corrupted images, and potential system hangs. The bus error was indicated by a 'frame decode timed out' message, followed by a 'bus error detected' alert. To resolve this, the VPUs must operate alternately, allowing successful multi-instance decoding of H.264 and HEVC. The G1 and G2 VPUs now share the same video4linux2 (v4l2) memory-to-memory device, enabling proper scheduling for decoding tasks.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version.
