Kirill Tkhai d2d2d4fb1f fuse: Fix use-after-free in fuse_dev_do_write() ... After we found req in request_find() and released the lock, everything may happen with the req in parallel: cpu0 cpu1 fuse_dev_do_write() fuse_dev_do_write() req = request_find(fpq, ...) ... spin_unlock(&fpq->lock) ... ... req = request_find(fpq, oh.unique) ... spin_unlock(&fpq->lock) queue_interrupt(&fc->iq, req); ... ... ... ... ... request_end(fc, req); fuse_put_request(fc, req); ... queue_interrupt(&fc->iq, req); Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Fixes: 46c34a348b ("fuse: no fc->lock for pqueue parts") Cc: <stable@vger.kernel.org> # v4.2		2018-09-28 16:43:21 +02:00
