  "title": "gnome-shell: A flaw was found in GNOME Shell",
  "description": "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\u0027s 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\u0027s session, and potentially disclose sensitive information from adjacent memory.",
