SCP7-931 : Security Advisory - linux - CVE-2018-5848

Created: Oct 28, 2018    Updated: Sep 17, 2019
Resolved Date: Sep 17, 2019
Found In Version: 7.0.0.5
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Kernel

Description

In the function wmi_set_ie() in the Linux kernel the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the ‘ie_len’ argument can cause a buffer overflow and thus a memory corruption leading to a system crash or other or unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
