CVE-2020-10234 Information

Description

The AscRegistryFilter.sys kernel driver in IObit Advanced SystemCare 13.2 allows an unprivileged user to send an IOCTL to the device driver. If the user provides a NULL entry for the dwIoControlCode parameter a kernel panic (aka BSOD) follows. The IOCTL codes can be found in the dispatch function: 0x8001E000 0x8001E004 0x8001E008 0x8001E00C 0x8001E010 0x8001E014 0x8001E020 0x8001E024 0x8001E040 0x8001E044 and 0x8001E048. \DosDevices\AscRegistryFilter and \Device\AscRegistryFilter are affected.
