Description

linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities Zhipeng Xie discovered that an infinite loop could be triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784) Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID lengths. A physically proximate attacker could use this to cause a denial of service (system crash).
