"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/rockchip: inno-hdmi: Switch to drmm_kzalloc()\n\nDriver makes use of drmm_encoder_init() to initialize the encoder and\nautomatically handle the cleanup by registering drm_encoder_cleanup()\nwith drmm_add_action().\n\nHowever, the internal structure containing the encoder part gets\nallocated with devm_kzalloc(), which happens while component_bind_all()\nis being called from Rockchip DRM driver. The component framework\nfurther ensures it is deallocated as part of releasing all the resources\nclaimed during bind, which is triggered from component_unbind_all().\n\nWhen the reference to the DRM device gets eventually dropped via\ndrm_dev_put() in rockchip_drm_unbind(), drmm_encoder_alloc_release()\nattempts to access the now released encoder structure, leading to\nuse-after-free.\n\nEnsure driver's internal structure is still reachable on encoder cleanup\nby switching from a device-managed allocation to a drm-managed one."
