CVE-2016-6787

CVE-2016-6787 describes a privilege escalation vulnerability in the Linux kernel's performance subsystem (kernel/events/core.c) affecting versions prior to 4.0. This flaw, stemming from improper lock management during migrations, allows local users to gain elevated privileges through a crafted application. With a CVSS v3.1 score of 7.0 (HIGH), it presents a significant risk due to its high impact on confidentiality, integrity, and availability, despite requiring high attack complexity and local access. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it has not garnered widespread attention.
