CVE-2010-3080

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.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
