Detailsinfo

A vulnerability was found in Linux Kernel (version unknown) and classified as critical. This issue affects the function isp1301_get_client of the component PHY Driver. The manipulation with an unknown input leads to a reference count vulnerability. Using CWE to declare the problem leads to CWE-911. The product uses a reference count to manage a resource, but it does not update or incorrectly updates the reference count. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: usb: phy: isp1301: fix non-OF device reference imbalance A recent change fixing a device reference leak in a UDC driver introduced a potential use-after-free in the non-OF case as the isp1301_get_client() helper only increases the reference count for the returned I2C device in the OF case. Increment the reference count also for non-OF so that the caller can decrement it unconditionally. Note that this is inherently racy just as using the returned I2C device is since nothing is preventing the PHY driver from being unbound while in use.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2025-71145 since 01/13/2026. Technical details are known, but no exploit is available.
