GNOME Shell vulnerabilities
3 known CVE vulnerabilities in GNOME Shell, translated and rated.
- CVE-2026-91786Medium
A flaw was found in GNOME Shell. When processing icons from a remote search provider via D-Bus, the system fails to validate the icon's declared dimensions against the actual data buffer size. A malicious or compromised remote search provider could exploit this by providing oversized icon dimensions, leading to an out-of-bounds read. This can cause the GNOME Shell process to crash, disrupting the user's session, and potentially disclose sensitive information from adjacent memory.
- CVE-2017-8288High
Versions of gnome-shell from 3.22 to 3.24.1 mishandle extensions that fail to reload, which can lead to leaving extensions enabled on the lock screen. This allows bystanders to launch applications and view information from those extensions.
- CVE-2014-7300High
GNOME Shell 3.14.x before 3.14.1 does not limit the aggregate memory consumption of active PrtSc requests, allowing nearby attackers to execute arbitrary commands on an unattended workstation.
