CVE-2015-8962
Published: 16 November 2016
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.
From the Ubuntu Security Team
It was discovered that the SCSI generic (sg) driver in the Linux kernel contained a double-free vulnerability. A local attacker could use this to cause a denial of service (system crash).
