Kees Cook 2b2cdec98e isdn: Disable IIOCDBGVAR ... [ Upstream commit 5e22002aa8 ] It was possible to directly leak the kernel address where the isdn_dev structure pointer was stored. This is a kernel ASLR bypass for anyone with access to the ioctl. The code had been present since the beginning of git history, though this shouldn't ever be needed for normal operation, therefore remove it.
