Title
net: usb: asix: validate PHY address before use
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: usb: asix: validate PHY address before use
The ASIX driver reads the PHY address from the USB device via
asix_read_phy_addr(). A malicious or faulty device can return an
invalid address (>= PHY_MAX_ADDR), which causes a warning in
mdiobus_get_phy():
addr 207 out of range
WARNING: drivers/net/phy/mdio_bus.c:76
Validate the PHY address in asix_read_phy_addr() and remove the
now-redundant check in ax88172a.c.
Severity ?
No CVSS data available.
