CVE-2023-52773

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix a NULL pointer dereference in amdgpu_dm_i2c_xfer() When ddc_service_construct() is called, it explicitly checks both the link type and whether there is something on the link which will dictate whether the pin is marked as hw_supported. If the pin isn't set or the link is not set (such as from unloading/reloading amdgpu in an IGT test) then fail the amdgpu_dm_i2c_xfer() call.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: corrige una desreferencia de puntero NULL en amdgpu_dm_i2c_xfer(). Cuando se llama a ddc_service_construct(), comprueba explícitamente tanto el tipo de enlace como si hay algo en el enlace que dictará si el pin está marcado como hw_supported. Si el pin no está configurado o el enlace no está configurado (por ejemplo, al descargar/recargar amdgpu en una prueba de IGT), falle la llamada amdgpu_dm_i2c_xfer().
