Subject: net: ax25: fix information leak to userland harder
From: Kees Cook <kees.cook@canonical.com>
commit 5b919f833d9d60588d026ad82d17f17e8872c7a9 upstream.
Commit fe10ae53384e48c51996941b7720ee16995cbcb7 adds a memset() to clear
the structure being sent back to userspace, but accidentally used the
wrong size.
