Linux Kernel icssm-prueth netops NULL deref crash
CVE-2026-99193 Published on October 28, 2026
net: ti: icssm-prueth: Move setting of netops to fix crash
In the Linux kernel, the following vulnerability has been resolved:
net: ti: icssm-prueth: Move setting of netops to fix crash
icssm_prueth_netdev_init() calls of_phy_get_and_connect() before
ndev->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").
