CVE-2025-38202

In the Linux kernel, the following vulnerability has been resolved: bpf: Check rcu_read_lock_trace_held() in bpf_map_lookup_percpu_elem() bpf_map_lookup_percpu_elem() helper is also available for sleepable bpf program. When BPF JIT is disabled or under 32-bit host, bpf_map_lookup_percpu_elem() will not be inlined. Using it in a sleepable bpf program will trigger the warning in bpf_map_lookup_percpu_elem(), because the bpf program only holds rcu_read_lock_trace lock. Therefore, add the missed check.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bpf: La comprobación de rcu_read_lock_trace_held() en bpf_map_lookup_percpu_elem() también está disponible para programas bpf en suspensión. Cuando BPF JIT está deshabilitado o en un host de 32 bits, bpf_map_lookup_percpu_elem() no se incluirá en línea. Su uso en un programa bpf en suspensión activará la advertencia en bpf_map_lookup_percpu_elem(), ya que el programa bpf solo mantiene el bloqueo rcu_read_lock_trace. Por lo tanto, se debe agregar la comprobación omitida.
