  "description": "In the Linux kernel, the following vulnerability has been resolved:  raid1: fix nr_pending leak in REQ_ATOMIC bad-block error path  In raid1_write_request(), each per-mirror loop iteration begins by incrementing rdev-\u003Enr_pending. If a REQ_ATOMIC write encounters a badblock within the requested range, the code jumps to err_handle without dropping the reference taken for the current mirror.  err_handle\u0027s cleanup loop will only decrements for k \u003C i and r1_bio-\u003Ebios[k] is non-NULL. The current slot is therefore skipped, leaving its nr_pending reference leaked permanently. The reference prevents the rdev from ever being removed, since raid1_remove_conf() refuses to remove an rdev with nr_pending \u003E 0.  Fix this by calling rdev_dec_pending() before jumping to err_handle.",
