## Description

In the Linux kernel, the following vulnerability has been resolved:  perf: Fix use-after-free when perf mmap() revival races with the last munmap()  perf_mmap_close() drops rb->mmap_count *without* holding event->mmap_mutex (the refcount_dec_and_test() right before the refcount_dec_and_mutex_lock() of event->mmap_count). A concurrent perf_mmap_rb() can slot its entire "revival" path into that window (perf_mmap holds event->mmap_mutex for its whole duration, including rb_alloc):    munmap side (perf_mmap_close)          mmap side (perf_mmap_rb)   -----------------------------------    --------------------------------   rb->mmap_count 1 -> 0   (no lock)      (holds event->mmap_mutex)                                          inc_not_zero(rb->mmap_count) fails                                          ring_buffer_attach(event, NULL)                                          rb_alloc() + attach new rb                                          refcount_set(&event->mmap_count, 1)   lock; event->mmap_count 1 -> 0   ring_buffer_attach(event, NULL)   ring_buffer_put() -> frees the *new* rb  The revival's refcount_set(&event->mmap_count, 1) is an invisible 1 -> 1 write: the close frees the just-revived buffer although the other process still has it mapped -- a page-level use-after-free allowing local privilege escalation to root by any unprivileged user (default kernel.perf_event_paranoid=2).  Swap the order of the two counter updates: event->mmap_count is dropped first via refcount_dec_and_mutex_lock(), so its 1 -> 0 transition and the ring_buffer_attach() stay serialized with perf_mmap(). rb->mmap_count == 0 then implies every event using the buffer is detached already, so the result of the rb->mmap_count drop can gate the remaining teardown directly and detach_rest is no longer needed.  An earlier fix for this race from Kyle Zeng and David Lee takes event->mmap_mutex around both counter updates [0]; here the not-last close stays lockless.
