  "description": "In the Linux kernel, the following vulnerability has been resolved:  powerpc/papr_scm: Fix leaking nvdimm_events_map elements  Right now \u0027char *\u0027 elements allocated for individual \u0027stat_id\u0027 in \u0027papr_scm_priv.nvdimm_events_map[]\u0027 during papr_scm_pmu_check_events(), get leaked in papr_scm_remove() and papr_scm_pmu_register(), papr_scm_pmu_check_events() error paths.  Also individual \u0027stat_id\u0027 arent NULL terminated \u0027char *\u0027 instead they are fixed 8-byte sized identifiers. However papr_scm_pmu_register() assumes it to be a NULL terminated \u0027char *\u0027 and at other places it assumes it to be a \u0027papr_scm_perf_stat.stat_id\u0027 sized string which is 8-byes in size.  Fix this by allocating the memory for papr_scm_priv.nvdimm_events_map to also include space for \u0027stat_id\u0027 entries. This is possible since number of available events/stat_ids are known upfront. This saves some memory and one extra level of indirection from \u0027nvdimm_events_map\u0027 to \u0027stat_id\u0027. Also rest of the code can continue to call \u0027kfree(papr_scm_priv.nvdimm_events_map)\u0027 without needing to iterate over the array and free up individual elements.",
