CVE-2024-40924
drm/i915/dpt: Make DPT object unshrinkable
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/dpt: Make DPT object unshrinkable
In some scenarios, the DPT object gets shrunk but
the actual framebuffer did not and thus its still
there on the DPT's vm->bound_list. Then it tries to
rewrite the PTEs via a stale CPU mapping. This causes panic.
