CVE-2023-53707: drm/amdgpu: Fix integer overflow in amdgpu_cs_pass1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix integer overflow in amdgpu_cs_pass1 The type of size is unsigned int, if size is 0x40000000, there will be an integer overflow, size will be zero after size *= sizeof(uint32_t), will cause uninitialized memory to be referenced later.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel AMDGPU driver flaw. A specially sized value can overflow during command submission handling, causing later use of uninitialized memory. The public bundle does not provide CVSS, impact scope, or confirmed exploitation, so business urgency depends on whether affected Linux systems use AMDGPU.

Executive priority

Prioritize based on AMDGPU presence and multi-user or shared-workload exposure. Without CVSS or exploitation evidence, this is not enough for emergency treatment everywhere, but affected GPU-enabled Linux fleets should be patched through normal kernel security update processes.

Technical view

The issue is in drm/amdgpu amdgpu_cs_pass1. An unsigned int size can overflow when multiplied by sizeof(uint32_t), wrapping to zero for size 0x40000000. The record says this can cause uninitialized memory to be referenced later. Stable kernel commits are referenced as the resolution.

Likely exposure

Likely exposure is Linux systems running affected kernel builds with the AMDGPU driver path available. The bundle lists Linux kernel versions and stable fixes, but does not map exact distribution package versions or hardware requirements beyond amdgpu context.

Exploitation context

The bundle does not report active exploitation, KEV listing, exploit availability, privilege requirements, or remote reachability. Treat exploitation context as incomplete. Because the flaw is in a kernel driver command-submission path, validation should focus on local systems using AMDGPU.

Researcher notes

The key evidence is the integer overflow description and three Linux stable commit references. Missing details include CVSS, CWE, practical impact, privilege boundary, and exploitability. Avoid assuming remote exploitation or specific distributions unless vendor advisories confirm them.

Mitigation direction

  • Update affected Linux kernels to versions containing the referenced stable fixes.
  • Check distribution advisories for backported kernel packages addressing CVE-2023-53707.
  • Prioritize hosts using AMDGPU or exposing GPU access to untrusted local users.
  • If patching is delayed, review vendor guidance for supported temporary controls.

Validation and detection

  • Inventory Linux hosts with AMDGPU hardware or the amdgpu module loaded.
  • Compare running kernel packages against vendor advisories for CVE-2023-53707.
  • Confirm the applicable stable fix commit is present in deployed kernel source or package notes.
  • Check whether untrusted users or workloads can access GPU device interfaces.
