Title
drm/i915/dpt: Make DPT object unshrinkable
Summary
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. [vsyrjala: Add TODO comment] (cherry picked from commit 51064d471c53dcc8eddd2333c3f1c1d9131ba36c)

There is no network-reachable path into `intel_dpt_create()`/`intel_dpt_resume()`.\nAC:L - The attacker controls every input: creating many DPT-backed framebuffers via ADDFB2 exhausts stolen memory to force the shrinkable shmem DPT path, anonymous memory allocation drives kswapd\u0027s `I915_SHRINK_ACTIVE` pass that evicts the DPT object, and logind lets an active local session initiate suspend/resume on demand, with unlimited retries.\nPR:L - An unprivileged local user with a graphical session holds an open primary DRM node (ADDFB2 has ioctl flags 0 \u2014 neither DRM_MASTER nor CAP_SYS_ADMIN is checked) and can allocate memory and request suspend; no root or capability is needed.\nUI:N - The bound framebuffer vma on the DPT vm\u0027s `bound_list` is the normal steady state of any running compositor, and the attacker can drive both the shrink and the suspend/resume itself via logind or the RTC wakealarm. No victim action is required.\nS:U - The dangling write and the resulting corruption are confined to the kernel\u0027s own address space and the same i915 device; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Corrupted/stale DPT page-table entries make the display engine fetch arbitrary physical pages for scanout, disclosing kernel and other-process memory, and the use-after-free write into reused vmalloc/ioremap space can be leveraged to expose memory contents.\nI:H - `dpt_insert_entries()` performs many 64-bit `writeq()` operations at an attacker-influenced index with attacker-influenced PTE values through a freed kernel mapping, a use-after-free/out-of-bounds write primitive usable for control-flow corruption once the VA range is reused.\nA:H - The fix commit states plainly that rewriting PTEs via the stale CPU mapping \"causes panic,\" and the related commit reports \"an immediate oops during hibernate,\" i.e. a full kernel crash on the resume path."
