Description OSIDB Bzimport 2026-10-23 12:46:24 UTC 
In the Linux kernel, the following vulnerability has been resolved:

bonding: fix the program leak when XDP is replaced

We need to release the reference on the old BPF prog, whether
we are going to no-prog, or replacing the prog with another.

Spotted by AI while running tests for the propagation series
(leaked programs were accumulating). Selftest will come in
the net-next series to avoid conflicts.
