Doc Text:
An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory.

Description Vasyl Kaigorodov 2015-01-08 12:09:46 UTC
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.
