Doc Text:	A flaw was found in the Linux kernel's USB subsystem. Specifically, within the omap2430 driver, a memory resource is prematurely released while still in use, leading to a use-after-free vulnerability. This could allow a local attacker to cause a system crash (denial of service) or potentially execute arbitrary code with elevated privileges.	Story Points:	---

Description OSIDB Bzimport 2026-07-19 16:01:50 UTC

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.
