CVE-2022-49486

Local service interruption via leaked device references

Published Feb 26, 2025 · Updated May 11, 2026

Resource leak in the Linux kernel before 5.19 allows local users to exhaust device references through failed SGTL5000 audio probes. The imx_sgtl5000_probe error paths retain the reference acquired by of_find_i2c_device_by_node() instead of releasing it with put_device(). Reachability requires the NXP i.MX SGTL5000 ASoC configuration and a failing probe path; repeated failures can exhaust kernel resources and interrupt service.
