Impact
In the Linux kernel, the following vulnerability has been resolved: nvdimm/btt: Free arena sub-allocations on discover_arenas() error path Memory allocated by btt_freelist_init(), btt_rtt_init(), and btt_maplocks_init() is not freed on some discover_arenas() error paths. This leaks memory when arena discovery fails. Add the missing kfree() calls to release the allocations before returning an error. [ as: commit message and log edits ]
