  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: phy: don\u0027t try to setup PHY-driven SFP cages when using genphy  We don\u0027t have support for PHY-driver SFP cages with the genphy code.  On top of that, it was found by sashiko that running sfp_bus_add_upstream() for genphy deadlocks, as for genphy the PHY probing runs under RTNL, which isn\u0027t the case for non-genphy drivers.  This problem was reproduced, and does lead to a deadlock on RTNL.  Before the blamed commit, the phy_sfp_probe() call was made by individual PHY drivers, so there was no way to get to the SFP probing path when using genphy.  Let\u0027s therefore only run phy_sfp_probe when not using genphy.",
