| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains an issue within the DRM/radeon driver related to the incorrect handling of device resource management. Specifically, calls to
drm put dev() persist in the probe error and device removal paths despite the driver's main structure allocation being changed to devm drm dev alloc(), which should handle freeing resources via devres. This results in a double-free scenario, leading to warnings such as 'refcount t: underflow; use-after-free' when the driver fails to probe. The issue stems from devres attempting to call drm put dev() after the driver has already done so.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
