Description

This security bulletin contains information about 1 vulnerability.


1) Memory leak (CVE-ID: CVE-2026-68220)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a memory leak in the imx8-isi crossbar and pipe cleanup paths when repeatedly loading and unloading the affected kernel module. A local user can trigger module initialization and cleanup cycles to cause a denial of service.

The issue occurs because subdevice active state allocated by v4l2_subdev_init_finalize() is not released during cleanup.
