- Summary
- CVE-2026-45989 affecting package kernel for versions less than 6.6.141.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
of: unittest: fix use-after-free in testdrv_probe()
The function testdrv_probe() retrieves the device_node from the PCI device, applies an overlay, and then immediately calls of_node_put(dn). This releases the reference held by the PCI core, potentially freeing the node if the reference count drops to zero. Later, the same freed pointer 'dn' is passed to of_platform_default_populate(), leading to a use-after-free.
The reference to pdev->dev.of_node is owned by the device model and should not be released by the driver. Remove the erroneous of_node_put() to prevent premature freeing.
