On failure that guard jumps to out_put_idev, below out_unlock_igroup, so it skips the mutex_unlock(), leaving the igroup lock held and deadlocking the next vDEVICE operation on that group. Jump to out_unlock_igroup instead. Join the discussion | GCVE Database | 08/28/2026, 09:31:49 UTC Added: 08/28/2026, 15:22:43 UTC |
