Summary
In the Linux kernel, the following vulnerability has been resolved:
orangefs: Fix kmemleak in orangefs_prepare_debugfs_help_string()
When insert and remove the orangefs module, then debug_help_string will
be leaked:
unreferenced object 0xffff8881652ba000 (size 4096):
comm "insmod", pid 1701, jiffies 4294893639 (age 13218.530s)
hex dump (first 32 bytes):
43 6c 69 65 6e 74 20 44 65 62 75 67 20 4b 65 79 Client Debug Key
77 6f 72 64 73 20 61 72 65 20 75 6e 6b 6e 6f 77 words are unknow
backtrace:
[<0000000004e6f8e3>] kmalloc_trace+0x27/0xa0
[<0000000006f75d85>] orangefs_prepare_debugfs_help_string+0x5e/0x480 [orangefs]

[<000000007790b19b>] entry_SYSCALL_64_after_hwframe+0x46/0xb0
When remove the module, should always free debug_help_string. Should
always free the allocated buffer when change the free_debug_help_string.
