nvdimm/btt: Free arenas on btt_init() error paths
Source: CVE Program / CVE List V5
Vulnerability Description
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. [ as: commit message and log edits ]
