Overview
CVE-2025-29933 describes a medium severity vulnerability affecting AMD uProf. This vulnerability stems from improper input validation, which could allow a local attacker to perform an out-of-bounds write operation. Successful exploitation of this vulnerability may lead to a system crash or denial of service.
Technical Details
The vulnerability resides within the input handling mechanisms of AMD uProf. Specifically, the application fails to adequately validate user-supplied input before using it to access memory. A local attacker with sufficient privileges could craft malicious input that causes uProf to write data beyond the intended memory buffer, resulting in memory corruption. This out-of-bounds write can overwrite critical system data, potentially leading to a crash or a denial-of-service condition.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-29933 is 5.5 (Medium). This score reflects the local attack vector and the potential impact of a denial of service. While the exploit requires local access, the ease of exploitation combined with the potential disruption warrants a medium severity rating.
Possible Impact
Exploitation of CVE-2025-29933 could have the following consequences:
- Denial of Service (DoS): A successful attack can cause AMD uProf to crash, rendering it unavailable for profiling and analysis tasks.
- System Instability: The out-of-bounds write could corrupt system memory, leading to unpredictable system behavior and potential crashes.
- Privilege Escalation (Potentially): While not explicitly stated, depending on the memory region overwritten, privilege escalation *might* be possible in some scenarios, though this is less likely given the description.
Mitigation or Patch Steps
AMD has released a security bulletin addressing this vulnerability. Users of AMD uProf are strongly advised to take the following steps:
- Update to the latest version of AMD uProf: AMD has likely released a patched version of uProf that resolves the input validation issue. Download and install the latest version from the official AMD website.
- Apply the security patch provided by AMD: If a patch is available separately from a full software update, apply it immediately.
- Monitor system logs: Regularly review system logs for any unusual activity or error messages related to AMD uProf.
Keep your system and software up to date to minimize the risk of exploitation.
