CVSS 7.099999904632568 HIGH
Record from redhat · Published October 14, 2026
A flaw was found in the Linux kernel's Open vSwitch (OVS) component. A race condition can occur during the destruction of a network device (netdev) tunnel, where the `ovs_netdev_tunnel_destroy()` function may attempt to release a device reference while other parts of the system are still actively using it. This timing issue, or race condition, could lead to system instability or a denial of service (DoS) due to improper resource handling.
