Title

drm/rockchip: dw_dp: Release core resources

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: dw_dp: Release core resources Core resources such as the DisplayPort AUX channel get initialized and registered during dw_dp_bind(), but are never unregistered, which may lead to memory leaks and/or use-after-free: [ 224.661371] BUG: KASAN: slab-use-after-free in device_is_dependent+0xe0/0x2b0 [ 224.662015] Read of size 8 at addr ffff00011aee8550 by task modprobe/658 [ 224.662612] [ 224.662752] CPU: 7 UID: 0 PID: 658 Comm: modprobe Not tainted 7.0.0-rc2-next-20260305 #14 PREEMPT [ 224.662759] Hardware name: Radxa ROCK 5B (DT) [ 224.662762] Call trace: [ 224.662764] show_stack+0x20/0x38 (C) [ 224.662772] dump_stack_lvl+0x6c/0x98 [ 224.662777] print_report+0x160/0x4b8 [ 224.662783] kasan_report+0xb4/0xe0 [ 224.662790] __asan_report_load8_noabort+0x20/0x30 [ 224.662796] device_is_dependent+0xe0/0x2b0 [ 224.662802] device_is_dependent+0x108/0x2b0 [ 224.662808] device_link_add+0x1f8/0x10b0 [ 224.662813] devm_of_phy_get_by_index+0x120/0x200 [ 224.662819] dw_dp_bind+0x34c/0xb10 [dw_dp] [ 224.662830] dw_dp_rockchip_bind+0x194/0x250 [rockchipdrm] [ 224.662864] component_bind_all+0x3a8/0x720 [ 224.662869] rockchip_drm_bind+0x120/0x390 [rockchipdrm] [ 224.662899] try_to_bring_up_aggregate_device+0x76c/0x838 [ 224.662904] component_master_add_with_match+0x1f4/0x230 [ 224.662909] rockchip_drm_platform_probe+0x420/0x538 [rockchipdrm] [ 224.662939] platform_probe+0xe8/0x168 [ 224.662945] really_probe+0x340/0x828 [ 224.662950] __driver_probe_device+0x2e0/0x350 [ 224.662954] driver_probe_device+0x80/0x140 [ 224.662959] __driver_attach+0x398/0x460 [ 224.662964] bus_for_each_dev+0xe0/0x198 [ 224.662968] driver_attach+0x50/0x68 [ 224.662972] bus_add_driver+0x2a0/0x4c0 [ 224.662977] driver_register+0x294/0x360 [ 224.662982] __platform_driver_register+0x7c/0x98 [ 224.662987] rockchip_drm_init+0xc4/0xff8 [rockchipdrm] Since a previous commit exported dw_dp_unbind() function in DW DP core library to take care of the necessary cleanup, use this in the component's unbind() callback, as well as in its bind() error path.

Vulnerability from github – Published: 2026-09-17 18:32 – Updated: 2026-09-17 18:32

Details

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

drm/rockchip: dw_dp: Release core resources

Core resources such as the DisplayPort AUX channel get initialized and registered during dw_dp_bind(), but are never unregistered, which may lead to memory leaks and/or use-after-free:

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
