CVE-2026-97901

The Linux kernel contains a vulnerability in the generic netlink controller where the policy dump keeps pointers to a target family's operation and policy tables in its callback state. Because Netlink only pins the module owning the dump callback (the controller's owner) rather than the target fa...
