CVE-2022-49953

Local denial of service via probe resource leak

Published Jun 18, 2025 · Updated May 11, 2026

Resource leak in Linux 5.16 through 5.19.7 and 6.0-rc1 through 6.0-rc3 allows local users to exhaust resources during CM3605 probing. The cm3605_probe() IRQ-error branch returns directly after a failed IRQ lookup instead of jumping to out_disable_aset, leaving the ASET GPIO asserted and the VDD regulator enabled. Exploitation requires local low-privileged access and a CM3605 device whose probe reaches the missing-IRQ path; repeated failures can interrupt system availability.
