CVE-2023-31331

Integrity loss or service interruption via repeated initialization

Published Feb 11, 2025 · Updated Feb 12, 2025

Improper access control in AMD Ryzen DRTM firmware allows local users to corrupt stack memory through repeated driver initialization. The firmware permits the same driver to be initialized multiple times and corrupts its stack state instead of rejecting the duplicate operation. Exploitation requires local high privileges and high-complexity conditions; successful corruption affects integrity or interrupts service without disclosing data.
