"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/bridge: synopsys: dw-dp: fix error paths of dw_dp_bind\n\nFix several issues in dw_dp_bind() error handling:\n\n1. Missing return after drm_bridge_attach() failure - the function\n continued execution instead of returning an error.\n\n2. Resource leak: drm_dp_aux_register() is not a devm function, so\n drm_dp_aux_unregister() must be called on all error paths after\n aux registration succeeds. This affects errors from:\n - drm_bridge_attach()\n - phy_init()\n - devm_add_action_or_reset()\n - platform_get_irq()\n - devm_request_threaded_irq()\n\n3. Bug fix: platform_get_irq() returns the IRQ number or a negative\n error code, but the error path was returning ERR_PTR(ret) instead\n of ERR_PTR(dp->irq).\n\nUse a goto label for cleanup to ensure consistent error handling."
