The Rocky Linux 10.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-202664775 advisory. kernel: can: bcm: add locking for bcmop runtime updates CVE-2025-38004 kernel: ipv6: add NULL checks for idev in SRv6 paths CVE-2026-23442 kernel: udp:...

kernel: vxlan: require CAP_NET_ADMIN in the device netns for changelink

A flaw was found in the Linux kernel's VXLAN Virtual Extensible LAN implementation. A local attacker, with CAPNETADMIN network administration capability in one network namespace, could exploit an incorrect privilege check in the rtnl changelink path. This allows the attacker to modify the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: vxlan: Fixed the nexthop hash size. The nexthop code expects a 31-bit hash, such as the one returned by fibmultipathhash and rt6multipathhash. Passing a 32-bit hash returned by skbgethash can lead to issues, especially when th...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: vxlan: It is required to have CAPNETADMIN in the device’s netns for the changelink function. A tunnel changelink operates on at most two netns: devnetdev and the sticky underlay netns vxlan-net. These two netns differ once the...

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: net:vxlan: Fixed a NULL dereference of ndtbl when IPv6 is disabled. When booting with the ‘ipv6.disable=1’ parameter, the ndtbl is never initialized because inet6init exits before ndiscinit is called, which is responsible for...

ROS-20261005-73-0119

The vulnerability of the routeshortcircuit function in the drivers/net/vxlan/vxlancore.c file of the Linux kernel network device driver is related to the use of pointers. Exploiting this vulnerability could allow an attacker to cause a system failure...

CVE-2026-97965

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN driver. When transmitting network packets on devices configured with Group Based Policy GBP metadata, the driver fails to properly initialize an internal stack variable if packet flags are omitted. This issue allows residual kern...

SUSE CVE-2026-97965

In the Linux kernel, the following vulnerability has been resolved: vxlan: initialize md in vxlanxmitone If a VXLAN device is configured with both VXLANFCOLLECTMETADATA and VXLANFGBP, and a packet is transmitted through it using an external iptunnelinfo that lacks the IPTUNNELVXLANOPTBIT flag, md...

CVE-2026-98023

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN driver. A local user with network administration privileges can cause a Denial of Service DoS by configuring dynamic forwarding database FDB entries that reference a shared next-hop group across multiple devices. This improper...

CVE-2026-98122

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN driver. A local unprivileged attacker can cause a denial of service DoS or potentially escalate privileges through memory corruption. This vulnerability occurs because the Multicast Database MDB subsystem improperly validates...
