LIN5-22367 : Security Advisory - linux - CVE-2016-10088

Created: Jan 12, 2017    Updated: May 29, 2018
Resolved Date: Jan 17, 2017
Found In Version: 5.0.1.38
Fix Version: 5.0.1.39
Severity: Standard
Applicable for: Wind River Linux 5
Component/s: Kernel

Description

The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576.
