Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xfrm_user: fix info leak in build_mapping()<br /> <br /> struct xfrm_usersa_id has a one-byte padding hole after the proto<br /> field, which ends up never getting set to zero before copying out to<br /> userspace. Fix that up by zeroing out the whole structure before<br /> setting individual variables.
