In the Linux kernel, the following vulnerability has been resolved: regmap: maple: free entry on mas_store_gfp() failure regcache_maple_write() allocates a new block (entry) to merge adjacent ranges and then stores it with mas_store_gfp(). When mas_store_gfp() fails, the new entry remains allocated and is never freed, leaking memory. Free entry on the failure path; on success continue freeing the replaced neighbor blocks (lower, upper).
