In the Linux kernel, the following vulnerability has been resolved:
nvdimm/btt: Free arenas on btt_init() error paths
The arenas allocated by discover_arenas() or create_arenas() are not freed on some error paths in btt_init(). This leaks memory when BTT initialization fails.
Call free_arenas() from the affected error paths to release the allocations.
