CVE-2024-38549

  2. Vulnerabilities (CVE)
  3. CVE-2024-38549
In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Add 0 size check to mtk_drm_gem_obj Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object of 0 bytes. Currently, no such check exists and the kernel will panic if a userspace application attempts to allocate a 0x0 GBM buffer. Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and verifying that we now return EINVAL.

Summary
  • (es) En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: drm/mediatek: Agregar verificación de tamaño 0 a mtk_drm_gem_obj Agregar una verificación a mtk_drm_gem_init si intentamos asignar un objeto GEM de 0 bytes. Actualmente, no existe tal verificación y el kernel entrará en pánico si una aplicación de espacio de usuario intenta asignar un búfer GBM 0x0. Probado intentando asignar un búfer GBM 0x0 en un MT8188 y verificando que ahora devolvemos EINVAL.
