CVE-2011-1476

Published: 25 March 2011

Integer underflow in the Open Sound System (OSS) subsystem in the Linux kernel before 2.6.39 on unspecified non-x86 platforms allows local users to cause a denial of service (memory corruption) by leveraging write access to /dev/sequencer.

From the Ubuntu Security Team

Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI interface. A local attacker on non-x86 systems might be able to cause a denial of service.

Notes

Author	Note
jdstrand	requires /dev/sequencer and OSS (not ALSA)
