CVE-2023-30772

System crash via charger teardown race

Published Apr 16, 2023 · Updated May 5, 2025

Use-after-free in the Linux kernel before 6.2.9 allows physically proximate attackers to crash the system by unplugging a DA9150 device. During da9150_charger_remove(), teardown frees the power-supply object without synchronously canceling pending otg_work, which later calls power_supply_changed() through the freed charger->usb pointer. Exploitation requires physical access to unplug the device during the race window, with a system crash as the established consequence.
