drm/i915/gvt: fix gvt debugfs destroy
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/i915/gvt: fix gvt debugfs destroy When gvt debug fs is destroyed, need to have a sane check if drm minor's debugfs root is still available or not, otherwise in case like device remove through unbinding, drm minor's debugfs directory has already been removed, then intel_gvt_debugfs_clean() would act upon dangling pointer like below oops. i915 0000:00:02.0: Direct firmware load for i915/gvt/vid_0x8086_did_0x1926_rid_0x0a.golden_hw_state failed with error -2 i915 0000:00:02.0: MDEV: Registered Console: switching to colour dummy device 80x25 i915 0000:00:02.0: MDEV: Unregistering BUG: kernel NULL pointer dereference, address: 00000000000000a0 PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP PTI CPU: 2 PID: 2486 Comm: gfx-unbind.sh Tainted: G I 6.1.0-rc8+ #15 Hardware name: Dell Inc.

The intervening `synchronize_rcu()`/`i915_gem_suspend()` guarantees the dentry is back on the slab freelist, and dentry-cache grooming is fully under the attacker\u0027s control.\nPR:L - The unprivileged local attacker supplies the exploitation half \u2014 spraying `dentry_cache` so the freed \"gvt\" dentry slot holds attacker-controlled `d_inode`/`d_subdirs` data before `simple_recursive_removal()` walks it; only the unbind trigger itself sits behind CAP_SYS_ADMIN, so the attacker needs no more than basic local access.\nUI:R - The freeing action is initiated by an administrator performing an i915 driver unbind or module removal \u2014 a routine GVT-g host maintenance operation (the reporter\u0027s own trace shows `gfx-unbind.sh`) \u2014 which the unprivileged attacker cannot invoke directly.\nS:U - The corruption occurs in host kernel memory and yields host kernel privileges; no VM, IOMMU, or sandbox boundary is crossed, so the vulnerable component and impacted component share the same security authority.\nC:H - Use-after-free on a `dentry` whose slot can be reoccupied by attacker-controlled data; `simple_recursive_removal()` dereferences `this-\u003ed_inode` and walks the `d_subdirs` list from that reused object, which can be steered into disclosing arbitrary kernel memory.\nI:H - The stale-dentry walk performs `dget()` (refcount write into the reallocated object), `inode_lock()` on an attacker-supplied inode pointer, and `dput()` on pointers read out of the reused slab slot \u2014 a write-and-free primitive suitable for heap corruption and control-flow hijack.\nA:H - Even without grooming, the bug reliably produces a kernel oops in `down_write()`/`simple_recursive_removal()` (`BUG: kernel NULL pointer dereference, address: 0x00000000000000a0`), killing the unbind task with locks held and leaving the machine in a broken state."
