CVE-2022-49241

Kernel resource exhaustion via leaked device-node references

Published Feb 26, 2025 · Updated May 11, 2026

A resource leak in the Linux kernel ASoC Atmel driver allows local users to exhaust kernel resources through repeated probe failures. sam9x5_wm8731_driver_probe increments a device-node reference with of_parse_phandle() but omits of_node_put() on its error paths. The affected Atmel audio driver must probe a matching device-tree configuration and enter an error path before the leak can interrupt service.
