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

What an attacker can do

A local attacker with low privileges can trigger a use-after-free error. NVD’s CVSS 3.1 assessment (base score 7.0/10) rates confidentiality, integrity and availability impact as high. The description does not state a further attacker outcome.
