CVE-2017-14991

Published: 03 October 2017

The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel before 4.13.4 allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for /dev/sg0.

From the Ubuntu security team

It was discovered that the generic SCSI driver in the Linux kernel did not properly initialize data returned to user space in some situations. A local attacker could use this to expose sensitive information (kernel memory).

Priority

Low

CVSS 3 base score: 5.5
