Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: hisilicon/qm - increase the memory of local variables<br /> <br /> Increase the buffer to prevent stack overflow by fuzz test. The maximum<br /> length of the qos configuration buffer is 256 bytes. Currently, the value<br /> of the &amp;#39;val buffer&amp;#39; is only 32 bytes. The sscanf does not check the dest<br /> memory length. So the &amp;#39;val buffer&amp;#39; may stack overflow.
