AI-suggested
An official patch is available and should be applied to affected Linux kernel versions. The fix is included in the Linux kernel security updates as referenced in the Ubuntu Security Notice USN-8278-1. Users should update their systems to the patched kernel versions to remediate this vulnerability.
Description
A double free vulnerability was identified and fixed in the Linux kernel's rockchip USB2 PHY driver (inno-usb2). The issue occurs in the rockchip_usb2phy_probe() function due to a duplicated call to of_node_put() when devm_request_threaded_irq() fails, causing a double free bug. This flaw has been addressed by modifying the control flow to avoid the duplicate release of the device node. The vulnerability affects specific Linux kernel versions and is rated medium severity. A patch is available as part of broader Linux kernel security updates.
