Subject: BUG in av7110_vbi_write()
Date: Wed, 13 May 2009 23:53:17 +0200 [thread overview]
Message-ID: <4A0B414D.5000106@googlemail.com> (raw)
Hi,
it seems there is a bug in av7110_vbi_write() (av7110_v4l.c). If an user mode application
tries to write more bytes than the size of the structure v4l2_slices_vbi_data,
copy_from_user() will overwrite parts of the kernel stack.
Regards,
Hartmut
