CVE-2026-97901

A flaw was found in the Linux kernel's Generic Netlink genetlink component. This flaw allows a local user to cause a Denial of Service DoS through a system crash. The vulnerability occurs because the kernel fails to maintain a reference to the target module during a policy dump that spans multipl...

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...
