CVE-2018-1782
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM GPFS (IBM Spectrum Scale 5.0.1.0 and 5.0.1.1) allows a local, unprivileged user to cause a kernel panic on a node running GPFS by accessing a file that is stored on a GPFS file system with mmap, or by executing a crafted file stored on a GPFS file system. IBM X-Force ID: 148805.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA local unprivileged user can trigger a kernel panic (complete system crash) on nodes running IBM GPFS (Spectrum Scale versions 5.0.1.0 and 5.0.1.1) by either memory-mapping a file via mmap() or executing a specially crafted file stored on a GPFS-mounted file system, causing denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if IBM Spectrum Scale (GPFS) is installedRun command to query the installed GPFS package version, such as 'mmfsadm version' or check the package manager for IBM Spectrum Scale componentsAffected if The product is not IBM Spectrum Scale/GPFS, the check does not apply
-
Verify the installed Spectrum Scale versionCompare your installed GPFS version against the affected versions 5.0.1.0 and 5.0.1.1 specificallyAffected if The installed version is exactly 5.0.1.0 or 5.0.1.1
-
Determine if GPFS file systems are mounted and activeCheck for mounted GPFS file systems using 'df -t gpfs' or 'mmmount' listings, indicating active GPFS usageAffected if No GPFS file systems are mounted, the vulnerable code path is not reachable
-
Confirm unprivileged user access to GPFS mounts existsVerify that local unprivileged users have read or execute access to GPFS-mounted directories, which enables the mmap() or file execution attack vectorAffected if All local users are restricted from accessing GPFS mounts, the attack surface is reduced
You are affected if IBM Spectrum Scale version 5.0.1.0 or 5.0.1.1 is installed with GPFS file systems actively mounted and accessible to unprivileged local users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade IBM Spectrum Scale to a version beyond 5.0.1.1 that includes the fix, or restrict local unprivileged user access to GPFS-mounted file systems until patching is feasible.
