Recent Gnome Shell Security Vulnerabilities
Linux distributions using CAP_SYS_NICE for gnome-shell may be exposed to a privilege escalation issue
CVE-2021-3982
5.5 - Medium
- April 29, 2022
Linux distributions using CAP_SYS_NICE for gnome-shell may be exposed to a privilege escalation issue. An attacker, with low privilege permissions, may take advantage of the way CAP_SYS_NICE is currently implemented and eventually load code to increase its process scheduler priority leading to possible DoS of other services running in the same machine.
Improper Check for Dropped Privileges
A locking protection bypass flaw was found in some versions of gnome-shell as shipped within CentOS Stream 8
CVE-2021-20315
6.1 - Medium
- February 18, 2022
A locking protection bypass flaw was found in some versions of gnome-shell as shipped within CentOS Stream 8, when the "Application menu" or "Window list" GNOME extensions are enabled. This flaw allows a physical attacker who has access to a locked system to kill existing applications and start new ones as the locked user, even if the session is still locked.
Improper Locking
An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4
CVE-2020-17489
4.3 - Medium
- August 11, 2020
An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.)
Insufficiently Protected Credentials

CVE-2019-3820
4.3 - Medium
- February 06, 2019
It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions.
