CVE-2026-53084

In the Linux kernel, the following vulnerability has been resolved: bpf: return VMA snapshot from task_vma iterator Holding the per-VMA lock across the BPF program body creates a lock ordering problem when helpers acquire locks that depend on mmap_lock: vm_lock -> i_rwsem -> mmap_lock -> vm_lock Snapshot the VMA under the per-VMA lock in _next() via memcpy(), then drop the lock before returning. The BPF program accesses only the snapshot. The verifier only trusts vm_mm and vm_file pointer
