Bug Report: https://bugzilla.kernel.org/show_bug.cgi?id=89101 Linux Version [3.17-rc1] Configuration: Default configuration for x86 Function (reserve_range) in file (drivers/pnp/system.c) allocates pointer (regionid) on line (32) and passes it to function (__request_region) through the macros: (request_region) at line (38) or (request_mem_region) at line (40). However, if the resource (res) is allocated through (__request_region) function, then the pointer (res->name) points to the allocated pointer (regionid). Then, there is no way in function (free_resource) or function (release_resource) to free the pointer (regionid) or (res->name). Thus, causing a potential memory leak!
