CVE-2019-15663Public exploit

Kernel memory disclosure via unchecked IOCTL offset

Published Mar 20, 2020 · Updated Aug 5, 2024

Out-of-bounds read in Rivet Killer Control Center before 2.1.1352 allows local users with admin rights to read kernel memory via a driver request. The KfeCo10X64.sys handler for IOCTL 0x120404 uses an attacker-supplied offset for a memory operation without validation, allowing the read to cross the intended buffer boundary. Administrator access is required, and the disclosed primitive supports privilege escalation only when chained with other flaws.
