In the Linux kernel, the following vulnerability has been resolved:
net: phy: clean the sfp upstream if phy probing fails
Sashiko reported that we don't call sfp_bus_del_upstream() in the probe
failure path, so let's add it, otherwise the sfp-bus is left with a
dangling 'upstream' field, that may be used later on during SFP events.
This issue existed before the generic phylib sfp support, back when
drivers were calling phy_sfp_probe themselves.

A flaw was found in the Linux kernel's network PHY (Physical Layer) driver. When a PHY probing operation fails, the system does not properly clean up the SFP (Small Form-Factor Pluggable) upstream connection. This oversight leaves a dangling reference in the SFP bus, which could be acce
