If it succeeds, pnfs_put_layout_hdr(lo) is called before trace_pnfs_update_layout(), which still references 'lo'. This results in a use-after-free when the tracepoint accesses lo's fields. Fix this by moving the tracepoint call before pnfs_put_layout_hdr(lo). Join the discussion | GCVE Database | 07/19/2026, 12:30:23 UTC Added: 07/19/2026, 19:38:21 UTC |
