CVE-2026-74615 vxlan: do not arm the ageing timer on a device that is down

In the Linux kernel, the following vulnerability has been resolved: vxlan: do not arm the ageing timer on a device that is down vxlanchangelink arms vxlan-agetimer whenever the requested ageing interval differs from the configured one: if conf.ageinterval != vxlan-cfg.ageinterval...

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...
