CVE-2023-1629Public exploit

Local kernel corruption via arbitrary address write

Published Mar 25, 2023 · Updated Aug 2, 2024

Memory corruption in Jiangmin Antivirus 16.2.2022.418 allows local users to write kernel memory through the kvcore.sys IOCTL handler. The 0x222010 handler accepts a caller-supplied address in its input structure and writes to that address without restricting it to a safe buffer. Local users can open the KvCoreCtrl device and corrupt kernel structures, causing a system crash or enabling broader kernel-memory manipulation.
