Description
In the Linux kernel, the following vulnerability has been resolved:
phylib: fix potential use-after-free
Commit bafbdd527d56 ("phylib: Add device reset GPIO support") added call
to phy_device_reset(phydev) after the put_device() call in phy_detach().
The comment before the put_device() call says that the phydev might go
away with put_device().
Fix potential use-after-free by calling phy_device_reset() before
put_device().
