Description

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.
