kernel: ipvlan: inherit needed_headroom and needed_tailroom from phy_dev

A flaw was found in the Linux kernel's ipvlan component. The ipvlan devices do not properly inherit neededheadroom and neededtailroom from the physical device phydev. This can lead to insufficient space being reserved for packet headers and trailers, potentially causing memory corruption, such as...

CVE-2026-74744 ipvlan: inherit needed_headroom and needed_tailroom from phy_dev

In the Linux kernel, the following vulnerability has been resolved: ipvlan: inherit neededheadroom and neededtailroom from phydev ipvlan devices inherit hardheaderlen from phydev during ipvlaninit, but leave neededheadroom and neededtailroom set to 0. When the underlying phydev or stacked lower...

In the Linux kernel, the following vulnerability has been resolved: ipvlan: inherit neededheadroom and neededtailroom from phydev ipvlan devices inherit hardheaderlen from phydev during ipvlaninit, but leave neededheadroom and neededtailroom set to 0. When the underlying phydev or stacked lower...

CVE-2026-74744

CVE-2026-74744 affects the Linux kernel ipvlan subsystem. During ipvlan_init(), ipvlan devices inherit hard_header_len from the physical device but leave needed_headroom and needed_tailroom set to zero. When the underlying device requires extra space for headers or trailers (e.g., macsec, ipsec, ...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises from the fact that ipvlan devices do not inherit neededheadroom and neededtailroom from phydev. As a result, insufficient space is reserved for the headers and tails of data packets during upper-layer calculations. This coul...
