n the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Atom Integrated System Info v2_2 for DCN35 New request from KMD/VBIOS in order to support new UMA carveout model. This fixes a null dereference from accessing Ctx->dc_bios->integrated_info while it was NULL. DAL parses through the BIOS and extracts the necessary integrated_info but was missing a case for the new BIOS version 2.3.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Atom Integrated System Info v2_2 para DCN35 Nueva solicitud de KMD/VBIOS para admitir el nuevo modelo de exclusión UMA. Esto corrige una desreferencia nula al acceder a Ctx->dc_bios->integrated_info mientras era NULL. DAL analiza el BIOS y extrae la información integrada necesaria, pero faltaba un caso para la nueva versión 2.3 del BIOS.
