LIN1018-6707 : Security Advisory - linux - CVE-2020-10781

Created: Sep 16, 2020    Updated: Oct 27, 2020
Resolved Date: Oct 22, 2020
Found In Version: 10.18.44.1
Fix Version: 10.18.44.20
Severity: Standard
Applicable for: Wind River Linux LTS 18
Component/s: Kernel

Description

A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.
