CVE-2026-89824

Resource leak via unreleased I2C adapter reference

Published Sep 16, 2026 · Updated Sep 16, 2026

Resource leak in Linux kernels containing cc5a3fc041f0 causes I2C adapter references to persist after panel-edp setup failures. In drivers/gpu/drm/panel/panel-edp.c, panel_edp_probe acquires the DDC adapter but failed to register cleanup before returning on probe deferral, and the same reference survived driver unbind when ddc-i2c-bus redundantly pointed to the AUX DDC bus. Exposure requires the panel-edp driver and that device-tree configuration; failed probes or unbinds retain references and can prevent clean adapter teardown.
