Description

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:
