Description Andrej Nemec 2017-07-12 10:11:44 EDT
The intr function in sound/oss/msnd_pinnacle.c in the Linux kernel 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.
