CVE-2024-35928 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init()

This ensures that the memory mapped by ioremap for adev->rmmio is properly handled in amdgpu_device_init(). If the function exits early due to an error the memory is unmapped. If the function completes successfully the memory remains mapped.

Reported by smatch: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:4337 amdgpu_device_init() warn: ‘adev->rmmio’ from ioremap() not released on lines: 403540454051405840684337
