Attack conditions (Source advisory, CVSS 3.1): Local · Low privileges required · No user interaction required

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

What an attacker can do

Source advisory’s CVSS 3.1 assessment (base score 7.8/10) rates confidentiality, integrity and availability impact as high. NVD’s CVSS 3.1 assessment (base score 5.5/10) rates confidentiality and integrity impact as none; availability impact as high. The description does not specify what an attacker can achieve beyond these rated impacts.
