DEBIAN-CVE-2026-99196: Null Pointer Dereference
In the Linux kernel, the following vulnerability has been resolved: net: au1000: move setting of netops to fix crash au1000probe() calls au1000miiprobe(), which connects the PHY, before dev->netdevops is assigned. phyattachdirect() -> phylinktopoaddphy() reads dev->netdevops through netdevneedopslock() since the commit in question, so probing crashes with a NULL pointer dereference when CONFIGNETSHAPER is enabled. Assign netdevops before the PHY attach, as was done for emac in commit 7c9f391ec89c ("net: emac: move setting of netops to fix crash").
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Assign dev->netdev_ops before au1000_probe() calls au1000_mii_probe() to attach the PHY.
Linux kernel au1000 driver dev->netdev_ops assignment order = assign before PHY attach
