Answer in brief
CVE-2026-98966 records a Unknown severity vulnerability in bonding: fix the program leak when XDP is replaced. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
