Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel before 4.4 allows local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call.

Weakness

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