CVE-2026-98007

A flaw was found in the Linux kernel. A privileged local user can cause a Denial of Service DoS by loading a specially crafted BPF Berkeley Packet Filter program that passes a pointer value instead of a scalar number as the loop iteration count to the bpfloop function. Because the kernel's BPF...

CVE-2026-98007

The Linux kernel contains a vulnerability in the bpf_loop() helper function where the nr_loops argument is incorrectly declared as ARG_ANYTHING. This allows privileged programs to pass pointer values instead of scalars. Because the verifier marks these registers as precise, passing a pointer trig...
