CVE-2026-46109 Details
Description
In the Linux kernel, the following vulnerability has been resolved: usb: ulpi: fix memory leak on ulpi_register() error paths Commit 01af542392b5 ("usb: ulpi: fix double free in ulpi_register_interface() error path") removed kfree(ulpi) from ulpi_register_interface() to fix a double-free when device_register() fails. But when ulpi_of_register() or ulpi_read_id() fail before device_register() is called, the ulpi allocation is leaked. Add kfree(ulpi) on both error paths to properly clean up the allocation.
A memory leak vulnerability has been identified in the USB ULPI (Universal Serial Bus Ultra-Low-Pin Interface) driver of the Linux kernel. This issue arises in the 'ulpi_register' function, where the 'ulpi' allocation is not properly freed if certain error conditions occur before the device is registered. The vulnerability affects the Linux kernel stable tree and has been addressed by adding a cleanup step to free the leaked memory on error paths.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been fixed.
