Description

This security bulletin contains information about 1 vulnerability.

1) Improper control of a resource through its lifetime (CVE-ID: CVE-2026-53340)

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

CVSSv4: 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/E:U/U:Clear

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

The vulnerability exists due to improper state management in i2c_imx_runtime_suspend() and i2c_imx_runtime_resume() when handling runtime power management state transitions. A local user can trigger runtime suspend and subsequent hardware access to cause a denial of service.

The issue can leave the clock disabled after a suspend failure, causing a system crash when the hardware is subsequently accessed.
