    Hello,

Linux kernel built with the iso9660 file system(CONFIG_ISO9660_FS) support is 
vulnerable to an information leakage flaw. This could occur while accessing 
data on an iso9660 image with RockRidge extension reference(ER) records.

An unprivileged user/process could use this flaw to leak (=~255)kernel memory 
bytes.

Upstream fix:
