Hi Greg, There are two important v4l2-core fixes on the patches merged this week by Linux. 1) media: v4l2-core: fix size of devnode_nums[] bitarray This patch correct a regression against Kernel 4.16. It affects notebooks with advanced Synaptics mice (and similar touch devices). On those devices, the pad produces an image with is handled via V4L2. Without this patch, the input driver OOPSes at probing time: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a95845ba184b854106972f5d8f50354c2d272c06 2) v4l2-compat-ioctl32: don't oops on overlay This patch complements the security fix we've made at the V4L2 core compat32 logic. It fixes an illegal use of an __user pointer without first convert into a Kernel pointer with get_user(). It wasn't detect before, as it uses an obscure streaming mode of V4L2 (overlay mode): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=85ea29f19eab56ec16ec6b92bc67305998706afa This one should go all the way down to stable Kernels. Here, I was able to reproduce the bug with both upstream Kernel and Kernel 3.18. The patch applied without any conflicts on both. Could you please add both on your next set of -stable releases? Thanks, Mauro
