CVE-2026-68205

The CVE-2026-68205 details a Linux kernel issue in media: v4l2-fwnode where v4l2_async_register_subdev_sensor() could overwrite the sensor driver’s owner with NULL due to THIS_MODULE resolving to the v4l2-fwnode module (or NULL when built-in). This prevented the sensor module’s reference count fr...

PT-2026-69605

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the v4l2-fwnode component where the helper function v4l2 async register subdev sensor incorrectly overwrites the subdevice owner. This occurs because the function call...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: media: i2c: ov5647: Initialize subdev before controls In the function ov5647initcontrols, we call v4l2getsubdevdata, but this initialization is actually done by v4l2i2csubdevinit within the probe function. Currently, this happens...
