Linux kernel: pmdomain: imx93-blk-ctrl: Extract PHY as shared domain for DSI/CSI

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.

What happened

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.

About this data

This record was ingested from a data source. Retrieved: Oct 30, 2026, 14:52 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
