Linux Kernel Aeroflex Netops NULL Deref Crash (CONFIG_NET_SHAPER)
CVE-2026-99194 Published on October 28, 2026
net: ethernet: aeroflex: move setting of netops to fix crash
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: aeroflex: move setting of netops to fix crash
greth_of_probe() calls greth_mdio_init(), which connects the PHY,
before dev->netdev_ops is assigned. phy_attach_direct() ->
phy_link_topo_add_phy() reads dev->netdev_ops through
netdev_need_ops_lock() since the commit in question, so probing crashes
with a NULL pointer dereference when CONFIG_NET_SHAPER is enabled.
Assign netdev_ops before the PHY attach, as was done for emac in commit
7c9f391ec89c ("net: emac: move setting of netops to fix crash").
