CVE-2026-23116: pmdomain: imx8m-blk-ctrl: Remove separate rst and clk mask for 8mq vpu

Published Feb 14, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

pmdomain: imx8m-blk-ctrl: Remove separate rst and clk mask for 8mq vpu

For i.MX8MQ platform, the ADB in the VPUMIX domain has no separate reset and clock enable bits, but is ungated and reset together with the VPUs. So we can't reset G1 or G2 separately, it may led to the system hang. Remove rstmask and clkmask of imx8mqvpublkctldomaindata. Let imx8mqvpupowernotifier() do really vpu reset.

Frequently Asked Questions

1

Which systems are exposed to this issue?

The issue applies to Linux kernel systems using the i.MX8MQ platform and its VPUMIX domain. The affected behavior involves attempts to reset the G1 or G2 VPU separately.

2

What does an attacker need to exploit the issue?

The CVSS vector indicates local access and low privileges are required. No user interaction is required.

3

What is the impact of successful exploitation?

The issue can cause a system hang, resulting in high availability impact. The supplied CVSS vector indicates no confidentiality or integrity impact.

4

What should be done if patching is not immediately possible?

Avoid separately resetting the G1 or G2 VPU on affected i.MX8MQ systems, since the ADB is reset and ungated together with the VPUs. A patch is available to remove the separate reset and clock masks and use the VPU power notifier for reset behavior.
