The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel before 4.5.5 mishandles NM (aka alternate name) entries containing \0 characters, which allows local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem.

Security readout for executives and security teams

CVE-2016-4913 is an old Linux kernel flaw in ISO9660/Rock Ridge filename handling. A local user could use a specially crafted ISO filesystem to make the kernel expose sensitive memory, with other impact left unspecified. It is not listed in KEV, and the supplied sources do not show active exploitation. Exposure is most likely on legacy Linux systems that allow local users, removable media, or automated workflows to mount untrusted ISO9660/Rock Ridge filesystems. Internet-facing exposure is not indicated by the supplied sources. Treat this as a legacy kernel hygiene issue unless your environment exposes untrusted local users or media-handling workflows. Patch through normal kernel maintenance, but prioritize shared Linux hosts, build systems, kiosks, and systems processing user-supplied ISO images. Mitigation focus: Apply vendor kernel security updates covering CVE-2016-4913.; Confirm legacy kernels include the upstream fix or a distro backport.; Restrict untrusted users from mounting ISO9660 or Rock Ridge filesystems..
