CVE-2026-93676: Red Hat Enterprise Linux 10

Low severity, CVSS 3.2. EPSS: 0.1% chance of exploitation in the next 30 days.

xdg-dbus-proxy incorrectly filters D-Bus broadcast messages, bypassing configured path, interface, and member restrictions. This allows a sandboxed Flatpak application to intercept broadcast signals on the D-Bus session bus and AT-SPI bus that should be restricted, potentially exposing sensitive information to unauthorized applications.

Affected products

• Red Hat Red Hat Enterprise Linux 10
