Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: usb: asix_devices: add phy_mask for ax88772 mdio bus<br /> <br /> Without setting phy_mask for ax88772 mdio bus, current driver may create<br /> at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f.<br /> DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy<br /> device will bind to net phy driver. This is creating issue during system<br /> suspend/resume since phy_polling_mode() in phy_state_machine() will<br /> directly deference member of phydev-&gt;drv for non-main phy devices. Then<br /> NULL pointer dereference issue will occur. Due to only external phy or<br /> internal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud<br /> the issue.
