Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
A lack of input validation in Realtek SD card reader driver before 10.0.26100.21374 through the implementation of the IOCTL_SCSI_PASS_THROUGH control of the SD card reader driver allows an attacker to write to predictable kernel memory locations, even as a low-privileged user.
