Affected: Alpaquita:stream: linux-lts

In the Linux kernel, the following vulnerability has been resolved:

drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove()

Attempting to access driver data in the platform driver ->remove() callback may lead to a null pointer dereference since there is no guaranty that the component ->bind() callback invoking platform_set_drvdata() was executed.

A common scenario is when Rockchip DRM driver didn't manage to run component_bind_all() because of an (unrelated) error causing early return from rockchip_drm_bind().

Drop the unnecessary call to platform_get_drvdata() and, instead, reference the target device structure via platform_device.

Ein Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen nicht näher spezifizierten Angriff durchzuführen, darunter möglicherweise Speicherbeschädigungen, die Offenlegung oder Manipulation von Daten sowie Denial-of-Service-Zustände.
