Open vSwitch netdev Tunnel Destroy
The vulnerability of the ovsnetdevtunnelDestroy function in the net/openvswitch/vport-netdev.c module, which supports Open vSwitch routers in the Linux operating system, is related to the lack of protection for sensitive data. Exploiting this vulnerability could allow an attacker to compromise th...
Ubuntu 22.04 LTS / Pro Realtime 22.04 LTS : Linux kernel (IBM) vulnerabilities (USN-8658-2)
The remote Ubuntu 22.04 LTS / Pro Realtime 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8658-2 advisory. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This...
kernel: net: openvswitch: reject oversized nested action attrs
A flaw was found in Open vSwitch in the Linux kernel. Improper handling of oversized nested action attributes can lead to a truncated length field, which could be exploited by a local attacker to alter kernel memory. This alteration might result in the disclosure of sensitive information or a loc...

CVE-2026-74701
A flaw was found in the Open vSwitch component of the Linux kernel. When a specially crafted packet with ETHPTEB protocol arrives on an ARPHRDNONE device, the keyextract function does not properly verify the Ethernet header length. This oversight allows a remote attacker to trigger a kernel bug,...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: rejecting negative ifindex values Recent changes in net-next commit 759ab1edb56c refactored the handling of pre-assigned ifindex values. This led to a latent issue in ovs. ovs does not validate ifindex values,...
CVE-2026-74664
A flaw was found in the Linux kernel's Open vSwitch component. When processing flow updates, the ovsflowcmdnew function preallocates a reply buffer based on the request's flow identifier. If a shorter User Flow ID UFID is provided, but the system matches an existing flow with a longer key...
SUSE CVE-2026-74664
In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: reallocate update replies for mismatched IDs ovsflowcmdnew preallocates the optional reply skb before it takes ovsmutex and before it knows which existing flow will be updated. That is normally fine because the...
SUSE CVE-2026-74701
In the Linux kernel, the following vulnerability has been resolved: net/openvswitch: check Ethernet header length in keyextract When a packet arrives on an ARPHRDNONE device e.g. TUN, ovsflowkeyextract trusts the user-provided skb-protocol field: if it is ETHPTEB, the packet is classified as...
