CVE-2020-10234: Iobit Advanced Systemcare

Medium severity, CVSS 6.5. EPSS: 3.3% chance of exploitation in the next 30 days.

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.
