CVE-2023-52661

Local service interruption via leaked clock references

Published May 17, 2024 · Updated May 11, 2026

Resource leakage in the Tegra RGB display driver in Linux allows local users to interrupt service through a failed device probe. In tegra_dc_rgb_probe(), an error after acquiring the pll_d2_out0 clock returns without calling clk_put(), leaving the acquired clock reference unreleased. Reachability requires a Tegra display configuration, local access, and failure of the subsequent clock lookup; the published record reports availability impact only.
