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...

Rocky Linux 8 [CIQ] Security Update: kernel-rt / kernel-rt-core / kernel-rt-debug / kernel-rt-debug-core / etc Multiple Vulnerabilities (crlsa-2026_68532)

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-202668532 advisory. kernel: ipvlan: Make the addrslock be per port CVE-2026-23103 kernel: xfrm: hold dev ref until after transportfinish NFHOOK CVE-2026-31663 kernel:...

ROS-20260918-73-0115

The vulnerability of Linux operating system’s ipvlan kernel components is related to insufficient blocking measures. Exploiting this vulnerability can allow an attacker to cause service failures...

kernel: ipvlan: Make the addrs_lock be per port

A race condition vulnerability was found in the Linux kernel's ipvlan driver. The per-device addrslock was incorrectly used instead of a per-port lock, and some code paths ipvlanopen/ipvlanclose failed to acquire the lock entirely. For IPv6 address changes that don't require RTNL lock, concurrent...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: ipvlan: Added a helper function for ipvlanroutev6outbound. This was inspired by reports from syzbot, which used multiple ipvlan devices in their stacks. The stack size required in ipvlanprocessv6outbound was reduced by moving...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipv6: Added lwtunnel encap size for all siblings in the nexthop calculation. In the function rt6nlmsgsize, the length of nexthop is calculated by multiplying the nexthop length of fib6info with the number of siblings. However, if...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by the lack of skb-cb initialization in the ipvlan network driver. The vulnerability is exploitable if CONFIGIPVLAN is...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ipvlan: Fixed bugs that occurred outside the bounds of the allowed values, caused by the absence of skb-macheader. If an AFPACKET socket is used to send packets through ipvlan, and the default xmit function of the AFPACKET socket...

Linux Distros Unpatched Vulnerability : CVE-2026-80733

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: remove WARNONONCE from skmcloop skmcloop can be called for sockets that are neither AFINET nor AFINET6 e.g. AFPACKET sockets when sending packets via...

SUSE CVE-2026-80733

In the Linux kernel, the following vulnerability has been resolved: net: remove WARNONONCE from skmcloop skmcloop can be called for sockets that are neither AFINET nor AFINET6 e.g. AFPACKET sockets when sending packets via raw/packet socket over virtual devices such as VRF or ipvlan. In such case...
