Description Andrej Nemec 2017-06-02 08:54:44 UTC
It was found that drivers/media/video/videobuf-vmalloc.c in the Linux kernel does not initialize videobuf_mapping data structures, which allows local users to trigger an incorrect count value and videobuf leak via unspecified vectors.

Upstream patch:


Comment 1 Andrej Nemec 2017-06-02 08:58:39 UTC

This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 6, 7 and Red Hat Enterprise MRG.

Red Hat Enterprise Linux 5 is now in Extended Life-cycle Support phase of the support and maintenance life cycle. This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates.
