Privilege Escalation Vulnerability in GNOME Shell on Linux Distributions

CVE-2021-3982

What is CVE-2021-3982?

A privilege escalation vulnerability affects GNOME Shell in Linux distributions that utilize CAP_SYS_NICE. An attacker with low privileges can exploit the improper implementation of CAP_SYS_NICE, enabling them to increase the process scheduler priority of their code. This may lead to denial of service (DoS) for other applications running on the same system, potentially disrupting the normal operations of the affected environment.
