CVE-2015-5466Public exploit

Local privilege escalation via arbitrary kernel write

Published Jan 15, 2020 · Updated Aug 6, 2024

Privilege escalation in Silicon Integrated Systems XGI VGA Display Manager 6.14.10.1090 allows local users to execute arbitrary kernel code. The xrvkp.sys handler for IOCTL 0x96002404 accepts attacker-controlled source data and destination addresses, creating a write-what-where condition. A local low-privileged process can overwrite HalDispatchTable function pointers and execute code with kernel privileges; the published proof of concept also demonstrates a system crash.
