CVE-2026-53232

Description

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.
