The intr function in sound/oss/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.
