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

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

What an attacker can do

NVD’s CVSS 3.1 assessment (base score 7.1/10) rates confidentiality and availability impact as high; integrity impact as none. Source advisory’s CVSS 3.1 assessment (base score 7.1/10) rates confidentiality and availability impact as high; integrity impact as none. The description does not specify what an attacker can achieve beyond these rated impacts.
