The driver in IOBit Unlocker 1.1.2 allows a low-privileged user to unlock a file and kill processes (even ones running as SYSTEM) that hold a handle, via IOCTL code 0x222124.

IOBit Advanced SystemCare Free 13.5.0.263 allows local users to gain privileges for file deletion by manipulating the Clean & Optimize feature with an NTFS junction and an Object Manager symbolic link.

IMFForceDelete.sys in IObit Malware Fighter 6.2 allows a low privileged user to send IOCTL 0x8016E000 along with a user defined string to a file; that file will be promptly deleted regardless of access controls.

SmartDefragDriver.sys (2.0) in IObit Smart Defrag 6 never frees an executable kernel pool that is allocated with user defined bytes and size when IOCTL 0x9C401CC0 is called. This kernel pointer can be leaked if the kernel pool becomes a "big" pool.

SmartDefragDriver.sys (2.0) in IObit Smart Defrag 6 never frees an executable kernel pool that is allocated with user defined bytes and size when IOCTL 0x9C401CC4 is called. This kernel pointer can be leaked if the kernel pool becomes a "big" pool.

RegFilter.sys in IOBit Malware Fighter 6.2 is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E044 with a size larger than 8 bytes. This can lead to denial of service or code execution with root privileges.

RegFilter.sys in IOBit Malware Fighter 6.2 is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E048 with a size larger than 8 bytes. This can lead to denial of service or code execution with root privileges.

RegFilter.sys in IOBit Malware Fighter 6.2 is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E040 with a size larger than 8 bytes. This can lead to denial of service or code execution with root privileges.

RegFilter.sys in IOBit Malware Fighter 6.2 is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E05C with a size larger than 8 bytes. This can lead to denial of service or code execution with root privileges.

RegFilter.sys in IOBit Malware Fighter 6.2 and earlier is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E010. This can lead to denial of service (DoS) or code execution with root privileges.
