In the Linux kernel, the following vulnerability has been resolved: drm/drv: Fix potential memory leak in drm_dev_init() drm_dev_init() will add drm_dev_init_release() as a callback. When drmm_add_action() failed, the release function won't be added. As the result, the ref cnt added by device_get() in drm_dev_init() won't be put by drm_dev_init_release(), which leads to the memleak. Use drmm_add_action_or_reset() instead of drmm_add_action() to prevent memleak. unreferenced object 0xffff88810bc0c800 (size 2048): comm "modprobe", pid 8322, jiffies 4305809845 (age 15.292s) hex dump (first 32 bytes): e8 cc c0 0b 81 88 ff ff ff ff ff ff 00 00 00 00 ................ 20 24 3c 0c 81 88 ff ff 18 c8 c0 0b 81 88 ff ff $] __kmalloc+0x4b/0x1c0 [] platform_device_alloc+0x2d/0xe0 [] platform_device_register_full+0x24/0x1c0 [] 0xffffffffa0736051 [] do_one_initcall+0x7a/0x380 [] do_init_module+0x5c/0x230 [] load_module+0x227d/0x2420 [] __do_sys_finit_module+0xd5/0x140 [] do_syscall_64+0x3f/0x90 [] entry_SYSCALL_64_after_hwframe+0x63/0xcd
