CVE-2014-7300

CVE-2014-7300 describes a denial-of-service vulnerability in GNOME Shell versions 3.14.x before 3.14.1, affecting various Red Hat Enterprise Linux products. This flaw allows a physically proximate attacker to bypass the screen lock and execute arbitrary commands on an unattended workstation. By repeatedly requesting screenshots, the attacker can trigger the Linux kernel's Out-Of-Memory (OOM) killer, leading to a temporary screen lock outage and shell access. With a CVSS score of 7.2, this vulnerability is considered high severity due to its local attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.
