Описание
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().
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.
Отчет
This issue affects TI VPE video processor on OMAP. v4l2_device_register succeeds but probe returns early without unregister on missing resource. Embedded OMAP VPE only.
