The kernel-rt is vulnerable to Information Disclosure. Kees Cook and Steve Beattie discovered a race condition in the /proc code in the Linux kernel. This could lead to information in the â/proc/[pid]/mapsâ and â/proc/[pid]/smapsâ files being leaked to users (who would otherwise not have access to this information) during ELF loading. This could help a local attacker bypass the ASLR security feature.
