CVE-2022-50407

In the Linux kernel, the following vulnerability has been resolved:

crypto: hisilicon/qm - increase the memory of local variables

Increase the buffer to prevent stack overflow by fuzz test. The maximum

length of the qos configuration buffer is 256 bytes. Currently, the value

of the 'val buffer' is only 32 bytes. The sscanf does not check the dest

memory length. So the 'val buffer' may stack overflow.
