Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Prevent ubuf size overflow The ubuf size calculation may overflow, resulting in an undersized allocation and possible memory corruption. Use check_add_overflow() helpers to validate the size calculation before allocation.

No race condition or special conditions beyond attacker control are required.\nPR:L - The ioctl is defined with flags 0 (no DRM_ROOT_ONLY), so any user who can open the accel device node can trigger it. On systems with AMD XDNA hardware, logged-in desktop users typically have access via the render group.\nUI:N - No user interaction is needed; the attacker directly issues the ioctl.\nS:U - The vulnerability is a kernel memory corruption within the kernel\u0027s security authority; no cross-boundary escape (VM, IOMMU) is involved.\nC:H - The heap buffer overflow writes page structure pointers beyond the allocated array, corrupting adjacent kernel heap objects. This memory corruption can be leveraged to read arbitrary kernel memory.\nI:H - The heap buffer overflow corrupts kernel heap metadata and adjacent objects, which can be exploited for arbitrary write primitives and code execution via heap spraying techniques.\nA:H - The heap corruption will cause kernel crashes (oops/panic) when corrupted objects are subsequently accessed."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
