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 asixreadphyaddr(). A malicious or faulty device can return an invalid address (>= PHYMAXADDR), which causes a warning in mdiobusgetphy(): addr 207 out of range WARNING: drivers/net/phy/mdiobus.c:76 Validate the PHY address in asixreadphy_addr() and remove the now-redundant check in ax88172a.c.
