Title
drm/vmwgfx: Return the correct value in vmw_translate_ptr functions
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Return the correct value in vmw_translate_ptr functions Before the referenced fixes these functions used a lookup function that returned a pointer. This was changed to another lookup function that returned an error code with the pointer becoming an out parameter. The error path when the lookup failed was not changed to reflect this change and the code continued to return the PTR_ERR of the now uninitialized pointer. This could cause the vmw_translate_ptr functions to return success when they actually failed causing further uninitialized and OOB accesses.

With CONFIG_INIT_STACK_ALL_ZERO (default on most modern distros), the uninitialized vmw_bo is deterministically NULL, making PTR_ERR return 0 every time.\nPR:L - The ioctl is marked DRM_RENDER_ALLOW, meaning any user with access to the render node can trigger it. Render nodes are typically accessible to unprivileged local users on desktop/VM systems.\nUI:N - No user interaction is required; the attacker directly issues the ioctl with a crafted command buffer.\nS:U - The vulnerability affects the kernel within its own security authority. While this is in a VM guest driver, exploitation stays within the guest kernel boundary.\nC:H - The uninitialized pointer dereference leads to OOB memory accesses, potentially reading arbitrary kernel memory contents.\nI:H - The uninitialized pointer is passed to vmw_bo_placement_set and vmw_validation_add_bo which perform write operations, enabling memory corruption that could be leveraged for code execution.\nA:H - Dereferencing an uninitialized or invalid pointer in kernel context causes a kernel oops/crash, confirmed by the commit message describing \"uninitialized and OOB accesses.\""

With CONFIG_INIT_STACK_ALL_ZERO (default on most modern distros), the uninitialized vmw_bo is deterministically NULL, making PTR_ERR return 0 every time.\nPR:L - The ioctl is marked DRM_RENDER_ALLOW, meaning any user with access to the render node can trigger it. Render nodes are typically accessible to unprivileged local users on desktop/VM systems.\nUI:N - No user interaction is required; the attacker directly issues the ioctl with a crafted command buffer.\nS:U - The vulnerability affects the kernel within its own security authority. While this is in a VM guest driver, exploitation stays within the guest kernel boundary.\nC:H - The uninitialized pointer dereference leads to OOB memory accesses, potentially reading arbitrary kernel memory contents.\nI:H - The uninitialized pointer is passed to vmw_bo_placement_set and vmw_validation_add_bo which perform write operations, enabling memory corruption that could be leveraged for code execution.\nA:H - Dereferencing an uninitialized or invalid pointer in kernel context causes a kernel oops/crash, confirmed by the commit message describing \"uninitialized and OOB accesses.\""

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
