Sažetak |
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):
