The snd_msnd_interrupt function in sound/isa/msnd/msnd_pinnacle.c in the Linux kernel through 4.11.7 allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a "double fetch" vulnerability.

Security readout for executives and security teams

CVE-2017-9984 affects an older Linux kernel sound driver. A local user could trigger an out-of-bounds access condition, causing denial of service or unspecified other impact. Business urgency is mainly for legacy Linux systems where this driver is present and local users or workloads are not fully trusted. Exposure appears limited to Linux systems running kernels through 4.11.7 with the affected msnd Pinnacle ISA sound driver built or loaded. The source bundle does not provide complete distribution-specific package coverage beyond referencing Ubuntu USN-3754-1. Treat this as a legacy exposure and hardening issue, not a broad internet-facing emergency. Prioritize shared Linux systems, multi-user environments, and unsupported kernels where local denial of service would affect business operations. Mitigation focus: Update affected Linux kernels using vendor-supported packages.; Review the referenced upstream kernel commit for the corrective change.; Check Ubuntu USN-3754-1 if managing affected Ubuntu systems..
