  3. CVE-2024-26662
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix 'panel_cntl' could be null in 'dcn21_set_backlight_level()' 'panel_cntl' structure used to control the display panel could be null, dereferencing it could lead to a null pointer access. Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn21/dcn21_hwseq.c:269 dcn21_set_backlight_level() error: we previously assumed 'panel_cntl' could be null (see line 250)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: la solución 'panel_cntl' podría ser nula en 'dcn21_set_backlight_level()'. La estructura 'panel_cntl' utilizada para controlar el panel de visualización podría ser nula, desreferenciarla podría conducir a un acceso de puntero nulo. Corrige lo siguiente: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn21/dcn21_hwseq.c:269 Error de dcn21_set_backlight_level(): previamente asumimos que 'panel_cntl' podría ser nulo (consulte la línea 250)
