Overview
CVE-2025-52538 is a high-severity vulnerability affecting the AMD XOCL driver. This vulnerability stems from improper input validation, which can allow a local attacker to trigger an integer overflow condition. Successful exploitation could lead to a loss of confidentiality or availability on the affected system.
Technical Details
The vulnerability resides within the XOCL driver, which is a component used for [Provide a brief, general explanation of what the XOCL driver does – replace this bracketed text. If the function of the driver is unknown, state “The specific function of the XOCL driver where the vulnerability exists is currently undisclosed in public sources.”]. The inadequate input validation allows a malicious actor with local access to supply crafted input that exceeds the driver’s expected range. This overflow can then corrupt memory, leading to unpredictable behavior, including system crashes or potential information disclosure.
The specific input vector and vulnerable function are [If the specific function and input are known, provide them here. Otherwise, state “Specific details regarding the vulnerable function and input vector have not been publicly disclosed as of the date of this article.”]. The vulnerability can be triggered by [If the method of triggering the vulnerability is known, provide it here. Otherwise, state “The exact method to trigger the vulnerability is not publicly available, but likely involves manipulating specific parameters passed to the driver.”].
CVSS Analysis
This vulnerability has been assigned a CVSS score of 8.0, indicating a HIGH severity. The CVSS vector is likely [Provide the likely CVSS vector string, e.g., CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H. If unknown, state “The specific CVSS vector string is not currently publicly available.”]. This high score reflects the potential for significant impact on affected systems.
Possible Impact
Successful exploitation of CVE-2025-52538 could have severe consequences, including:
- Loss of Confidentiality: An attacker might be able to gain access to sensitive data stored in memory or on disk.
- Loss of Availability: The integer overflow could lead to a system crash or denial-of-service condition, rendering the system unusable.
- Potential for Privilege Escalation: While not explicitly stated, depending on the context, an attacker might be able to leverage the vulnerability to elevate their privileges on the system (this is less likely given the lack of mention in the description).
Mitigation or Patch Steps
The primary mitigation strategy is to apply the patch provided by AMD. Users should:
- Visit the AMD Security Bulletin AMD-SB-8014 to download and install the appropriate driver update for their system.
- Carefully review the instructions provided by AMD to ensure a successful patch installation.
- Monitor AMD’s security advisories for any further updates or recommendations related to this vulnerability.
- As a general security best practice, keep all system software and drivers up to date.
