CVE-2026-74615

A flaw was found in the Linux kernel's vxlan module. An unprivileged user can trigger a use-after-free vulnerability by performing specific network-related operations within a new user and network namespace. This can lead to system instability, causing a denial of service, and potentially allowin...

CVE-2026-74615

CVE-2026-74615 is a slab-use-after-free in the Linux kernel vxlan module. The root cause is that vxlan_changelink() arms the FDB ageing timer without a netif_running() check, so on a never-brought-up device the timer persists after free_netdev() releases the vxlan_dev struct, causing the timer co...

CVE-2026-74523

A flaw was found in the Linux kernel's qede network driver. When a qede Network Interface Card NIC with VXLAN/GENEVE tunnel ports experiences a transmit TX timeout, a deadlock can occur in the driver's recovery process. This deadlock prevents the system's networking control plane from responding,...

CVE-2026-74474

A flaw was found in the Linux kernel's vxlan module. This vulnerability arises from the incorrect handling of network packet headers during data transmission. Specifically, certain functions within the vxlan module fail to properly account for the initial part of the network packet, known as the...

CVE-2026-74473

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN implementation. An incorrect buffer length check in the routeshortcircuit function, specifically when using pskbmaypull, can lead to reading beyond the allocated buffer length. This occurs when processing IP headers in non-linear...

CVE-2026-74406

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN component. A race condition can occur where the udptunnelsockrelease function sets a socket's user data to NULL while the vxlangropreparereceive function is still actively using it. This could lead to a null pointer dereference,...

CVE-2026-74475

A flaw was found in the Linux kernel's VXLAN Virtual Extensible LAN implementation. An issue exists where the neighbor hardware address MAC address could be read incorrectly due to a lack of proper synchronization. This could lead to the system using a partially updated or corrupted MAC address,...
