------------------ From: Mathias Krause <[email protected]> [ Upstream commit 6865d1e834be84ddd5808d93d5035b492346c64a ] When filling the netlink message we miss to wipe the pad field, therefore leak one byte of heap memory to userland. Fix this by setting pad to 0. Signed-off-by: Mathias Krause <[email protected]> Signed-off-by: David S.
