CVE-2025-48521: CWE-416 Use After Free in AMD AMD Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics (formerly codenamed "Renoir")
Improper input validation in the AMD Secure Processor (ASP) PCI driver could allow a local attacker to trigger a Use-After-Free (UAF) condition, potentially resulting in a loss of platform integrity or crash.
AI Analysis
Technical Summary
This vulnerability involves improper input validation in the AMD Secure Processor PCI driver on AMD Ryzen 4000 Series Mobile Processors with Radeon Graphics (Renoir). The flaw allows a local attacker with low privileges to trigger a Use-After-Free condition, potentially compromising platform integrity or causing a crash. The CVSS 4.0 vector indicates local attack vector, low attack complexity, no user interaction required, and high impact on integrity and availability. No official remediation or patch information is currently available.
Potential Impact
A successful exploitation could result in loss of platform integrity or system crashes. The attacker must have local access and low privileges. There is no indication of remote exploitation or user interaction requirements. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limiting local access and monitoring for unusual system behavior may reduce risk.
