Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ip tunnel component where the options len variable is not initialized before being referenced. This can lead to a kernel panic due to a buffer overflow when using...
Astra Linux – Vulnerability in Linux
A flaw was discovered in the Linux kernel in versions prior to 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel. This allows anyone between the two endpoints to read the unencrypted...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: geneve: Fixed header validation in geneve6xmitskb. syzbot is able to trigger an uninit-value in genevexmit. Problem: While most IP tunnel helpers such as iptunnelgetdsfield use skbprotocolskb, true, pskbinetmaypull only uses...
Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: In the tunnels section, there’s no need to assume that the macheader is set when using skbtunnelcheckpmtu. The recently added debug in commit f9aefd6b2aa3 “net: warn if mac header was not set” identified a bug in...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: geneve: Make sure to pull the inner header in geneverx. syzbot triggered a bug in geneverx 1 The issue is similar to the one I fixed in commit 8d975c15c0cd: "ip6tunnel: Make sure to pull the inner header in ip6tnlrcv" We need ...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nfttunnel: fixed a type confusion issue with geneveopt. When handling multiple NFTATUNNELKEYOPTSGENEVE attributes, the parsing logic should process each geneveopt structure individually and compactly. Therefore, whe...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: net: fixed the integer overflow in the geneveopt structure’s length field. The struct geneveopt uses 5 bits to represent the length of each individual option. This means that the size of each option should be less than 128 bytes...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: geneve: Do not assume that the MAC header is set in genevexmitskb. We should not assume that the MAC header is present in the output path. Instead, use skbethhdr instead of ethhdr to fix the issue. sysbot reported the followin...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: UDP: Do not accept non-tunnel GSO packets that land in a tunnel. When rx-udp-gro-forwarding is enabled, UDP packets may be forwarded in a way that causes them to land in a tunnel. This can lead to various issues. udpgroreceive...
kernel: vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets
A flaw was found in the vmxnet3 virtual network device driver within the Linux kernel. When processing Geneve-encapsulated packets, the vmxnet3gethdrlen function can incorrectly interpret header information, leading to a mismatch between expected and actual packet protocols or IP versions. This c...

In the Linux kernel, the following vulnerabilities have been resolved: geneve: Fixed a use-after-free in genevefinddev. syzkaller reported a use-after-free in genevefinddev 0 without repro. geneveconfigure links the struct genevedev.next to netgenericnet, genevenetid-genevelist. The net here may...
Astra Linux – Vulnerability in OpenVSwitch
A flaw was discovered in Open vSwitch, where multiple versions are vulnerable to crafted Geneve packets, which may lead to a denial of service and invalid memory accesses. Triggering this issue requires that hardware offloading via the netlink path is enabled...
CVE-2026-89555
A flaw was found in the Linux kernel's Multiprotocol Label Switching MPLS subsystem. When processing specially crafted Geneve packets through an MPLS multipath setup, a use-after-free vulnerability occurs. This issue arises because a cached header pointer hdr is not reloaded after pskbmaypull...
