CVE-2025-22084 (opens in a new tab)Amendment
The Minimos security team deemed this advisory irrelevant for Minimos:latest.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-virt-doc package and not the linux-virt-doc package as distributed by Minimos.
In the Linux kernel, the following vulnerability has been resolved:
w1: fix NULL pointer dereference in probe
The w1_uart_probe() function calls w1_uart_serdev_open() (which includes devm_serdev_device_open()) before setting the client ops via serdev_device_set_client_ops(). This ordering can trigger a NULL pointer dereference in the serdev controller's receive_buf handler, as it assumes serdev->ops is valid when SERPORT_ACTIVE is set.
This is similar to the issue fixed in commit 5e700b384ec1 ("platform/chrome: cros_ec_uart: properly fix race condition") where devm_serdev_device_open() was called before fully initializing the device.
Fix the race by ensuring client ops are set before enabling the port via w1_uart_serdev_open().
