AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a stack overflow issue in the Linux kernel's crypto module for hisilicon/qm. The problem arises because a local buffer ('val buffer') used to store qos configuration data is only 32 bytes, but the maximum qos configuration buffer length can be up to 256 bytes. The sscanf function used to read data into this buffer does not check the destination memory length, which can cause the buffer to overflow the stack.
How can this vulnerability impact me? :
The stack overflow caused by this vulnerability can lead to memory corruption, which may allow an attacker to execute arbitrary code, cause a denial of service (system crash), or escalate privileges on the affected system.
