- Summary
- w1: fix NULL pointer dereference in probe
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
w1: fix NULL pointer dereference in probe
The w1uartprobe() function calls w1uartserdevopen() (which includes devmserdevdeviceopen()) before setting the client ops via serdevdevicesetclientops(). This ordering can trigger a NULL pointer dereference in the serdev controller's receivebuf handler, as it assumes serdev->ops is valid when SERPORTACTIVE is set.
This is similar to the issue fixed in commit 5e700b384ec1 ("platform/chrome: crosecuart: properly fix race condition") where devmserdevdevice_open() was called before fully initializing the device.
Fix the race by ensuring client ops are set before enabling the port via w1uartserdev_open().
