Improper control of a resource through its lifetime in Linux kernel - CVE-2026-64278

Vulnerability identifier: #VU139707

CSH Severity: Low

CVSS v4: 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]

CVE-ID: CVE-2026-64278

CWE-ID: CWE-664

Exploitation vector: Local access

Exploit availability: No public exploit available

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

The vulnerability exists due to improper resource state handling in the i2c-imx-lpi2c driver when processing I2C transfers during the suspend and resume noirq window. A local user can trigger an I2C transfer while controller resources are unavailable to cause a denial of service.

The issue occurs on some i.MX platforms when periodic workqueue activity continues across system suspend and resume.
