CVE-2022-48710

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix a possible null pointer dereference In radeon_fp_native_mode(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd. The failure status of drm_cvt_mode() on the other path is checked too.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/radeon: corrige una posible desreferencia del puntero null. En radeon_fp_native_mode(), el valor de retorno de drm_mode_duplicate() se asigna al modo, lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate(). Agregue una marca para evitar npd. También se verifica el estado de falla de drm_cvt_mode() en la otra ruta.
