CVE-2025-29951
HighSummary
A buffer overflow in the AMD Secure Processor (ASP) bootloader allows an attacker to overwrite memory, potentially leading to privilege escalation and arbitrary code execution.
Risk Assessment
The risk includes potential compromise of the secure processor, which could undermine system integrity and allow an attacker to operate with elevated privileges.
Recommendation
Apply the firmware update provided by the vendor immediately and monitor AMD security advisories for patches.
Other vulnerabilities in AMD Secure Processor
See all- CVE-2023-31323High
Type confusion in the AMD Secure Processor (ASP) could allow an attacker to pass a malformed argument to the External Global Memory Interconnect Trusted Agent (XGMI TA) leading to a memory safety violation potentially resulting in loss of confidentiality, integrity, or availability.
- CVE-2023-20514High
The vulnerability in AMD Secure Processor (ASP) stems from improper handling of parameters, allowing a privileged attacker to pass an arbitrary memory value to functions in the trusted execution environment. This could lead to arbitrary code execution.
- CVE-2021-46747High
Insufficient granularity of access control in ASP (AMD Secure Processor) may allow an attacker with an untrusted user space application to map sensitive SMN apertures leading to a potential escalation of privileges.
