CVE-2025-22105

Service interruption via incompatible XDP bond mode

Published Apr 16, 2025 · Updated Jun 1, 2026

Linux bonding allows local users to interrupt service by switching an XDP-loaded bond to an incompatible mode during cleanup. bond_option_mode_set accepts the unsupported mode transition, so dev_xdp_uninstall later reaches bond_xdp_set with an invalid mode and emits a kernel warning. Exploitation requires privileges to configure a bond and attach an XDP program inside a network namespace; the demonstrated consequence is the cleanup warning.
