- Summary
- net: phy: clean the sfp upstream if phy probing fails
- Details
-
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 sfpbusdel_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 physfpprobe themselves.
