CVE-2026-23358
Received Received - Intake
Use-After-Free in Linux Kernel AMDGPU Slot Reset Error Handling

Publication date: 2026-03-25

Last updated on: 2026-04-24

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix error handling in slot reset If the device has not recovered after slot reset is called, it goes to out label for error handling. There it could make decision based on uninitialized hive pointer and could result in accessing an uninitialized list. Initialize the list and hive properly so that it handles the error situation and also releases the reset domain lock which is acquired during error_detected callback. (cherry picked from commit bb71362182e59caa227e4192da5a612b09349696)

Executive Summary

This vulnerability exists in the Linux kernel's drm/amdgpu component related to error handling during a slot reset. If the device does not recover after a slot reset, the error handling code may access an uninitialized list due to an uninitialized hive pointer. This improper initialization can lead to incorrect behavior or potential crashes.

Impact Analysis

The vulnerability can cause the system to behave unpredictably or crash when error handling is triggered during a slot reset in the drm/amdgpu driver. This could lead to system instability or denial of service conditions if the device fails to recover properly.

Mitigation Strategies

The vulnerability has been resolved by fixing error handling in the drm/amdgpu component of the Linux kernel. To mitigate this vulnerability, you should update your Linux kernel to a version that includes the fix (cherry picked from commit bb71362182e59caa227e4192da5a612b09349696). This ensures proper initialization of the list and hive pointers during error handling and releases the reset domain lock correctly.
