CVE-2024-43886

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check in resource_log_pipe_topology_update [WHY] When switching from "Extend" to "Second Display Only" we sometimes call resource_get_otg_master_for_stream on a stream for the eDP, which is disconnected. This leads to a null pointer dereference. [HOW] Added a null check in dc_resource.c/resource_log_pipe_topology_update.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amd/display: agregar verificación nula en Resource_log_pipe_topology_update [POR QUÉ] Al cambiar de "Extender" a "Sólo segunda visualización", a veces llamamos a Resource_get_otg_master_for_stream en una secuencia para eDP, lo que está desconectado. Esto conduce a una desreferencia del puntero nulo. [CÓMO] Se agregó una verificación nula en dc_resource.c/resource_log_pipe_topology_update.
