Description OSIDB Bzimport 2025-03-27 17:04:13 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: mdio: validate parameter addr in mdiobus_get_phy()

The caller may pass any value as addr, what may result in an out-of-bounds
access to array mdio_map. One existing case is stmmac_init_phy() that
may pass -1 as addr. Therefore validate addr before using it.
