CVE-2018-14617

An issue was discovered in the Linux kernel. A NULL pointer dereference and panic in hfsplus_lookup() in the fs/hfsplus/dir.c function can occur when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

If the HFS+ filesystem is not in use, this module can be blacklisted and prevented from being loaded. See https://access.redhat.com/solutions/41278 for instructions on how to blacklist the 'hfsplus.ko' kernel module.
