In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve param->string when parsing mount options In bpf_parse_param(), keep the value of param->string intact so it can be freed later. Otherwise, the kmalloc area pointed to by param->string will be leaked as shown below: unreferenced object 0xffff888118c46d20 (size 8): comm "new_name", pid 12109, jiffies 4295580214 hex dump (first 8 bytes): 61 6e 79 00 38 c9 5c 7e any.8.\~ backtrace (crc e1b7f876): [] kmemleak_alloc+0x4b/0x80 [] __kmalloc_node_track_caller_noprof+0x36e/0x4a0 [] memdup_user+0x32/0xa0 [] strndup_user+0x46/0x60 [] __x64_sys_fsconfig+0x368/0x3d0 [] x64_sys_call+0xff/0x9f0 [] do_syscall_64+0x3b/0xc0 [] entry_SYSCALL_64_after_hwframe+0x4b/0x53
