CVE-2026-63906 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: musb: omap2430: Fix use-after-free in omap2430_probe() In omap2430_probe(), of_node_put(np) is called prematurely before the last access to np, leading to a use-after-free if the node's reference count drops to zero. Move the of_node_put() calls after the last use of np in both the success and error paths.
A use-after-free vulnerability has been identified in the Linux kernel's USB driver for the OMAP2430 platform. The issue arises in the 'omap2430_probe()' function, where the 'of_node_put(np)' call is made prematurely, before the last access to 'np'. This mismanagement can lead to a use-after-free condition if the reference count of the node drops to zero. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been fixed.
