## Technical details

An out-of-bounds (OOB) write vulnerability (CWE-787) exists in the AMD Platform Management Framework (PMF) Driver due to improper input validation. A local attacker with low privileges can provide crafted input to the driver to trigger a memory corruption event. Successful exploitation allows the attacker to overwrite sensitive kernel-mode memory, which can be leveraged to escalate privileges to SYSTEM or administrative levels. The vulnerability is reachable locally without user interaction. Users are advised to refer to AMD security bulletin AMD-SB-4015 for specific driver update versions.
