In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix null check for pipe_ctx->plane_state in dcn20_program_pipe This commit addresses a null pointer dereference issue in dcn20_program_pipe(). Previously, commit 8e4ed3cf1642 ("drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe") partially fixed the null pointer dereference issue. However, in dcn20_update_dchubp_dpp(), the variable pipe_ctx is passed in, and plane_state is accessed again through pipe_ctx. Multiple if statements directly call attributes of plane_state, leading to potential null pointer dereference issues. This patch adds necessary null checks to ensure stability.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Fix null check for pipe_ctx->plane_state in dcn20_program_pipe Esta confirmación soluciona un problema de desreferencia de puntero nulo en dcn20_program_pipe(). Anteriormente, el commit 8e4ed3cf1642 ("drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe") solucionó parcialmente el problema de desreferencia de puntero nulo. Sin embargo, en dcn20_update_dchubp_dpp(), se pasa la variable pipe_ctx y se accede nuevamente a plane_state a través de pipe_ctx. Varias declaraciones if llaman directamente a los atributos de plane_state, lo que lleva a posibles problemas de desreferencia de puntero nulo. Este parche agrega las comprobaciones nulas necesarias para garantizar la estabilidad.
