AI Analysis

Impact

An out-of-bounds write condition in the AMD Compressonator SDK can be triggered by a specially crafted DirectDraw Surface (DDS) file supplied by a local user or automated pipeline. The vulnerable code can corrupt heap data or terminate the application, leading to service disruption. The weakness is classified as CWE-787.

Affected Systems

The vulnerability affects the AMD Compressonator SDK; no specific versions are listed in the CNA data, so all deployments of the SDK should be treated as potentially affected until a patch is applied.

Risk and Exploitability

The CVSS score of 5.2 indicates moderate severity. The exploit probability metric (EPSS) is not available, and the issue is not listed in the CISA KEV catalog. Attack requires local access; therefore, the risk is limited to individuals who can run code on the affected system or supply crafted DDS files to a running application.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Check AMD’s product security bulletin for an available patch and apply it immediately.
  • Limit local users to only run trusted applications and prohibit the processing of unknown DDS files within automated pipelines.
  • If a patch is not yet available, disable or isolate DirectDraw Surface handling until the vulnerability is remediated.
