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.

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, and 5 as it did not include upstream commit 7034632d that introduced the problem. It did not affect Red Hat Enterprise MRG as the /dev/sequencer device file is restricted to root access only.
