Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: veth: The GRO flag is cleared when XDP is disabled, even when the device is disabled. The NETIFFGRO flag is set automatically when XDP is enabled, because both features use the same NAPI mechanism. The logic for clearing the...

CVE-2026-80846 xfrm: drop ESP-in-TCP packets with no ingress device

In the Linux kernel, the following vulnerability has been resolved: xfrm: drop ESP-in-TCP packets with no ingress device ESP-in-TCP receives records through the TCP strparser. handleesp restores skb-dev from the saved skbiif before passing the packet into the XFRM input path. Queued TCP data can ...

CVE-2026-80613

A flaw was found in the Linux kernel's veth component. An error in the rollback mechanism during XDP eXpress Data Path enablement can lead to a Networked Asynchronous Packet Interface NAPI structure not being properly deallocated. This results in a Use-After-Free UAF vulnerability, where freed...

CVE-2026-74742

A flaw was found in the Linux kernel's veth component. In a multi-queue setup without an eXpress Data Path XDP program attached, the vethpoll function incorrectly derives the index of the peer transmit TX queue to wake. This can cause a TX queue to stop indefinitely if it becomes full, as the...
