CVE-2010-3080

Published: 21 September 2010

Double free vulnerability in the snd_seq_oss_open function in sound/core/seq/oss/seq_oss_init.c in the Linux kernel before 2.6.36-rc4 might allow local users to cause a denial of service or possibly have unspecified other impact via an unsuccessful attempt to open the /dev/sequencer device.

From the Ubuntu security team

Tavis Ormandy discovered that the OSS sequencer device did not correctly shut down. A local attacker could exploit this to crash the system or possibly gain root privileges.
