CVE-2026-98038
The Linux kernel contains a vulnerability in the BPF subsystem where bpf_refcount_acquire() incorrectly treats certain borrowed RCU kptrs as owning references. Specifically, refcounted objects without a graph node appear as owning references even without an acquired state. This allows a program t...
