"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nof/overlay: don't leak fragment references when changeset init fails\n\ninit_overlay_changeset() stores the number of initialized fragments\nin ovcs->count only on full success. When find_target() or the\n__symbols__ lookup fails partway through, the target and overlay\nreferences taken for the fragments initialized so far are never\ndropped: free_overlay_changeset() bounds its cleanup loop by\novcs->count, which is still 0.\n\nStore the running count on the error path so free_overlay_changeset()\nputs whatever was set up. The store is guarded by ovcs->fragments\nbecause on the allocation-failure path cnt still holds the counting\npass total while there is no fragments array; everywhere else cnt\nonly counts fully-initialized fragments."
