CVE-2024-39481 Information

Description

In the Linux kernel the following vulnerability has been resolved:

media: mc: Fix graph walk in media_pipeline_start

The graph walk tries to follow all links even if they are not between pads. This causes a crash with e.g. a MEDIA_LNK_FL_ANCILLARY_LINK link.

Fix this by allowing the walk to proceed only for MEDIA_LNK_FL_DATA_LINK links.
