  "details": "In the Linux kernel, the following vulnerability has been resolved:  of/overlay: don't leak fragment references when changeset init fails  init_overlay_changeset() stores the number of initialized fragments in ovcs-\u003ecount only on full success. When find_target() or the __symbols__ lookup fails partway through, the target and overlay references taken for the fragments initialized so far are never dropped: free_overlay_changeset() bounds its cleanup loop by ovcs-\u003ecount, which is still 0.  Store the running count on the error path so free_overlay_changeset() puts whatever was set up. The store is guarded by ovcs-\u003efragments because on the allocation-failure path cnt still holds the counting pass total while there is no fragments array; everywhere else cnt only counts fully-initialized fragments.",
