Title
phylib: fix potential use-after-free
Summary
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().

additional chance conditions.\\nPR:L - Triggering requires CAP_NET_ADMIN to bring down or otherwise detach a PHY-backed interface, which is available to an unprivileged user via user namespaces/containers that have been given such a netdev, not only full init-namespace root.\\nUI:N - No separate victim action is required; the attacker who can perform the netdev/driver operation triggers the bug themselves.\\nS:U - Impact stays within the local kernel/host authority; this is a standard kernel UAF privilege-escalation class issue, not a VM/sandbox/IOMMU boundary escape.\\nC:H - Use-after-free of struct phy_device lets an attacker reclaim and control the object contents, enabling arbitrary kernel read primitives via the subsequent reset_gpio/reset_ctrl use.\\nI:H - The same UAF enables heap spraying and corruption of the freed phy_device so that mdio_device_reset()\u0027s gpiod/reset_control calls become arbitrary write/control-flow primitives.\\nA:H - Use-after-free of
