Description OSIDB Bzimport 2024-07-05 09:22:30 UTC 
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.
