Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw in the DRM encoder handling during unbinding, specifically within the drm/rockchip and dw hdmi components. This issue results in a use-after-free crash when a module is removed. The problem occurs because the DRM encoder's memory is freed before the main DRM device is destroyed. The fix involves moving encoder cleanup before disabling the clock, mirroring the bind-error path.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
