CVE-2026-98039

The Linux kernel contains a vulnerability in the BPF subsystem where map_kptr_match_type() fails to properly validate the MEM_PERCPU flag for BPF_KPTR_PERCPU fields. Because the subset test accepts allocations without the required flag, a plain bpf_obj_new() allocation can be stored in a __percpu...
