In the Linux kernel, the following vulnerability has been resolved: drm/msm/dp: Drop aux devices together with DP controller Using devres to depopulate the aux bus made sure that upon a probe deferral the EDP panel device would be destroyed and recreated upon next attempt. But the struct device which the devres is tied to is the DPUs (drm_dev->dev), which may be happen after the DP controller is torn down. Indications of this can be seen in the commonly seen EDID-hexdump full of zeros in the log, or the occasional/rare KASAN fault where the panel's attempt to read the EDID information causes a
