Official description

In the Linux kernel, the following vulnerability has been resolved: afs: Fix lack of locking around modifications of net->cells_dyn_ino Fix the lack of locking around modifications of net->cells_dyn_ino by taking net->cells_lock exclusively. This also requires to cell to be removed from net->cells_dyn_ino in afs_destroy_cell_work() rather than in afs_cell_destroy() as the latter runs in RCU cleanup context and sleeping locks cannot be taken there.
