Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
ubifs: Fix memory leak in ubifs_sysfs_init()
When insmod ubifs.ko, a kmemleak reported as below:
unreferenced object 0xffff88817fb1a780 (size 8): comm "insmod", pid 25265, jiffies 4295239702 (age 100.130s) hex dump (first 8 bytes): 75 62 69 66 73 00 ff ff ubifs... backtrace: [] slab_post_alloc_hook+0x9c/0x3c0 [] __kmalloc_track_caller+0x183/0x410 [] kstrdup+0x3a/0x80 [] kstrdup_const+0x66/0x80 [] kvasprintf_const+0x155/0x190 [] kobject_set_name_vargs+0x5b/0x150 [] kobject_set_name+0xbb/0xf0 [] do_one_initcall+0x14c/0x5a0 [] do_init_module+0x1f0/0x660 [] load_module+0x6d7e/0x7590 [] __do_sys_finit_module+0x19f/0x230 [] __x64_sys_finit_module+0x73/0xb0 [] do_syscall_64+0x35/0x80 [] entry_SYSCALL_64_after_hwframe+0x63/0xcd
When kset_register() failed, we should call kset_put to cleanup it.
