Description
This security bulletin contains information about 1 vulnerability.
1) Improper control of a resource through its lifetime (CVE-ID: CVE-2026-68205)
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 ownership handling in v4l2_async_register_subdev_sensor() when registering a V4L2 subdevice sensor asynchronously. A local user can trigger registration of a crafted or removable sensor driver module to cause a denial of service.
The issue can leave the sensor driver's module owner unset, allowing the module to be removed while the subdevice is still in use by a notifier such as a CSI-2 receiver bridge driver.
Remediation
Install update from vendor's website.
