CVE-2026-0432: CWE-276 Incorrect Default Permissions in AMD AMD Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics
CVE-2026-0432 is a high-severity vulnerability affecting AMD Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics. It involves incorrect default permissions in the installation directory of the AMD chipset driver, which could allow a local attacker with limited privileges to escalate their privileges and execute arbitrary code. The vulnerability has a CVSS 4.0 base score of 8.5, indicating a significant risk. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-0432) arises from incorrect default permissions set on the installation directory of the AMD chipset driver for Ryzen™ 4000 Series Mobile Processors with Radeon™ Graphics. Because of these permissions, an attacker with local access and limited privileges could potentially escalate their privileges to execute arbitrary code on the affected system. The CVSS 4.0 vector indicates the attack requires local access with low complexity and no user interaction, with high impact on confidentiality, integrity, and availability. No official remediation or patch has been documented yet.
Potential Impact
If exploited, this vulnerability could allow a local attacker to escalate privileges and execute arbitrary code, potentially compromising the affected system's confidentiality, integrity, and availability. However, there are no known exploits in the wild currently. The impact is significant given the high CVSS score and the nature of privilege escalation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit local access to trusted users only and monitor for suspicious activity related to the AMD chipset driver installation directory permissions.
