What an attacker can do

A local privileged attacker can trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure. Vendor/CNA’s CVSS 3.1 assessment (base score 6.7/10) rates confidentiality impact as high; integrity impact as none; availability impact as low. NVD’s CVSS 3.1 assessment (base score 6.0/10) rates confidentiality and availability impact as high; integrity impact as none.
