CVE-2025-21985

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-21985
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix out-of-bound accesses [WHAT & HOW] hpo_stream_to_link_encoder_mapping has size MAX_HPO_DP2_ENCODERS(=4), but location can have size up to 6. As a result, it is necessary to check location against MAX_HPO_DP2_ENCODERS. Similiarly, disp_cfg_stream_location can be used as an array index which should be 0..5, so the ASSERT's conditions should be less without equal.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Corrección de accesos fuera de los límites [QUÉ Y CÓMO] hpo_stream_to_link_encoder_mapping tiene un tamaño de MAX_HPO_DP2_ENCODERS(=4), pero la ubicación puede tener un tamaño de hasta 6. Por lo tanto, es necesario comparar la ubicación con MAX_HPO_DP2_ENCODERS. De igual forma, disp_cfg_stream_location puede usarse como un índice de matriz que debe ser de 0 a 5, por lo que las condiciones de ASSERT deben ser menores sin igual.
