CWE Code: 119
Vulnerability Type: privilege_escalation
CVSS Score: 7.2
CWE Name:  Improper Restriction of Operations within the Bounds of a Memory Buffer
Summary: local attackers can trigger a stack-based buffer overflow on vulnerable installations of antiy-avl atool security management v1.0.0.22. an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. the specific flaw exists within the processing of ioctl 0x80002000 by the irpfile.sys antiy-avl atool kernel driver. the bug is caused by failure to properly validate the length of the user-supplied data, which results in a kernel stack buffer overflow. an attacker can leverage this vulnerability to execute arbitrary code in the context of the kernel, which could lead to privilege escalation and a failed exploit could lead to denial of service.
