MIPI PHY Shared Domain Fix in Linux Kernel

Publication date: 2026-08-15

Last updated on: 2026-08-17

Assigner: kernel.org

Description

In the Linux kernel, the following vulnerability has been resolved: pmdomain: imx93-blk-ctrl: Extract PHY as shared domain for DSI/CSI The MIPI DSI and CSI domains share control bits for clock and reset, which can lead to incorrect behavior if one domain disables the shared resource while the other is still active. To fix the issue, introduce a shared MIPI PHY power domain to own the common resources and make DSI and CSI its subdomains. This ensures the shared bits are properly managed and not disabled while still in use.

Executive Summary

This vulnerability in the Linux kernel involves incorrect management of shared resources between MIPI DSI and CSI domains in the imx93-blk-ctrl power domain. The shared clock and reset control bits can be disabled prematurely while one domain is still active, causing incorrect behavior.

Detection Guidance

This vulnerability is specific to the Linux kernel's pmdomain subsystem for the i.MX93 BLK-CTRL. Detection requires checking kernel logs for errors related to MIPI DSI/CSI domains or shared PHY resources. Use commands like dmesg | grep -i 'mipi\|phy\|blk-ctrl' or journalctl -k | grep -i 'mipi\|phy\|blk-ctrl' to inspect system logs for related errors.

Impact Analysis

If exploited, this could lead to system instability or malfunction in devices using MIPI DSI and CSI interfaces, potentially causing display or camera failures, data corruption, or crashes in affected Linux systems.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it pertains to a Linux kernel power domain management issue in MIPI DSI/CSI interfaces. No evidence suggests data exposure or privacy risks.

Mitigation Strategies

Apply the latest Linux kernel update that includes the fix for this issue. If updating is not immediately possible, avoid using MIPI DSI and CSI interfaces simultaneously to reduce the risk of incorrect behavior. Monitor kernel logs for any related errors after applying changes.
