Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the packet function, there is a need to use a consistent value for hardheaderlen in non-ring send paths. The packetsnd function reads dev-hardheaderlen multiple times during allocation and construction of an skb. Device...

Important: kernel

Issue Overview: An issue in the Linux kernel's virtio-net/TAP networking path could allow an actor with privileged access inside a guest virtual machine to send specially crafted network packets that corrupt host kernel memory on KVM-based hypervisors running unpatched Linux kernel versions 4.4...

SUSE CVE-2026-90160

In the Linux kernel, the following vulnerability has been resolved: lwtbpf: Restore reserved headroom after xmit program ipfinishoutput2 expands an skb to LLRESERVEDSPACEdev before LWT xmit. An LWTXMIT BPF program can then modify the skb head and still return BPFOK, so bpfxmit rechecks the...

Linux Distros Unpatched Vulnerability : CVE-2026-90160

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - lwtbpf: Restore reserved headroom after xmit program ipfinishoutput2 expands an skb to LLRESERVEDSPACEdev before LWT xmit. An LWTXMIT BPF program can then modif...

DEBIAN-CVE-2026-90083

In the Linux kernel, the following vulnerability has been resolved: net/sched: actife: Only operate on Ethernet frames actife encapsulates/decapsulates the original Ethernet header and uses skb-dev-hardheaderlen as the length of that header. That is only correct for Ethernet devices: on a device...

CVE-2026-90160 lwt_bpf: Restore reserved headroom after xmit program

In the Linux kernel, the following vulnerability has been resolved: lwtbpf: Restore reserved headroom after xmit program ipfinishoutput2 expands an skb to LLRESERVEDSPACEdev before LWT xmit. An LWTXMIT BPF program can then modify the skb head and still return BPFOK, so bpfxmit rechecks the...

CVE-2026-90083

CVE-2026-90083 affects the Linux kernel's net/sched act_ife (IFE) traffic control action. The IFE action uses skb->dev->hard_header_len as the Ethernet header length, which is incorrect on non-Ethernet devices (e.g., PPP reports PPP_HDRLEN while nothing is stripped on ingress). When a packe...

CVE-2026-90160: Undefined Security Weakness
