  "title": "interconnect: Don\u0027t access req_list while it\u0027s being manipulated",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  interconnect: Don\u0027t access req_list while it\u0027s being manipulated  The icc_lock mutex was split into separate icc_lock and icc_bw_lock mutexes in [1] to avoid lockdep splats. However, this didn\u0027t adequately protect access to icc_node::req_list.  The icc_set_bw() function will eventually iterate over req_list while only holding icc_bw_lock, but req_list can be modified while only holding icc_lock. This causes races between icc_set_bw(), of_icc_get(), and icc_put().  Example A:    CPU0                               CPU1   ----                               ----   icc_set_bw(path_a)     mutex_lock(\u0026icc_bw_lock);                                      icc_put(path_b)                                        mutex_lock(\u0026icc_lock);     aggregate_requests()       hlist_for_each_entry(r, ...                                        hlist_del(...         \u003Cr = invalid pointer\u003E  Example B:    CPU0                               CPU1   ----                               ----   icc_set_bw(path_a)     mutex_lock(\u0026icc_bw_lock);                                      path_b = of_icc_get()                                        of_icc_get_by_index()                                          mutex_lock(\u0026icc_lock);                                          path_find()                                            path_init()     aggregate_requests()       hlist_for_each_entry(r, ...                                              hlist_add_head(...         \u003Cr = invalid pointer\u003E  Fix this by ensuring icc_bw_lock is always held before manipulating icc_node::req_list. The additional places icc_bw_lock is held don\u0027t perform any memory allocations, so we should still be safe from the original lockdep splats that motivated the separate locks.
