Doc Text:	A flaw was found in the Linux kernel's media Video Processing Engine (VPE) driver. This issue occurs during device initialization when a specific resource is unavailable, causing the device to remain improperly registered. As a result, system resources are not correctly released, which could lead to resource exhaustion or system instability. An attacker could potentially exploit this to cause a denial of service (DoS), making the system unresponsive or unavailable.	Story Points:	---

Description OSIDB Bzimport 2026-08-10 12:29:11 UTC

In the Linux kernel, the following vulnerability has been resolved:

media: ti: vpe: unwind v4l2 device registration on probe error

If the vpe_top resource is missing, vpe_probe() returns -ENODEV after
v4l2_device_register() has succeeded. Probe failures do not call the
driver's remove callback, so the v4l2 device remains registered on that
error path.

Route that failure through the existing v4l2_device_unregister() unwind
label, matching the other errors after v4l2_device_register().
