SB20260816522 - Improper control of a resource through its lifetime in Linux kernel pmdomain imx driver

Description

This security bulletin contains information about 1 vulnerability.

1) Improper control of a resource through its lifetime (CVE-ID: CVE-2026-72009)

CWE-ID: CWE-664 - Improper control of a resource through its lifetime

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper resource management in the imx93-blk-ctrl power domain handling for MIPI DSI and CSI when managing shared clock and reset resources. A local user can trigger concurrent use of the DSI and CSI domains to cause a denial of service.

The issue occurs because the two domains share control bits for clock and reset, so one domain may disable a resource while the other remains active.

Remediation

Install update from vendor's website.
