Vulnerability from github – Published: 2026-05-08 15:31 – Updated: 2026-05-15 18:30

Details

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.

Severity

5.5 (Medium)
