| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel related to a device reference imbalance within the ISP1301 USB PHY driver. A recent fix for a device reference leak in a UDC driver introduced a potential use-after-free issue in non-OF (Open Firmware) cases. The
isp1301 get client() helper function only increased the reference count for the returned I2C device in the OF case, leading to a potential use-after-free condition when the device is used outside of the OF context. The issue is inherently race-prone, as the PHY driver could be unbound while in use.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
