In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
media: platform: mtk-mdp3: Fix SCP device refcounting<\/p>\n
mdp_probe() first tries to get the SCP handle with scp_get(). When that
\nfails, it falls back to looking up the SCP platform device with
\n__get_pdev_by_id() and then reads its driver data.<\/p>\n
The fallback lookup returns the platform device with a reference, just
\nlike scp_get() does. However, the fallback path currently drops that
\nreference immediately after platform_get_drvdata(). The driver later
\nstill calls scp_put(mdp->scp) unconditionally from the probe error path
\nand from mdp_video_device_release(), which drops the SCP device
\nreference again.<\/p>\n
Keep the fallback reference until the existing scp_put() call, so that
\nthe fallback path follows the same ownership rules as the scp_get()
\npath.<\/p>\n","protected":false},"excerpt":{"rendered":"
