Attack conditions (NVD, CVSS 3.1): Local · High privileges required · No user interaction required

What an attacker can do

A local privileged attacker could use this flaw to overflow the kernel stack. Vendor/CNA’s CVSS 3.1 assessment (base score 6.0/10) rates confidentiality and integrity impact as high; availability impact as none. NVD’s CVSS 3.1 assessment (base score 6.7/10) rates confidentiality, integrity and availability impact as high.
