CVE-2026-91786 | BDVDB-2026-374473 Detail

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'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.
