CVE-2026-31508
The CVE-2026-31508 issue affects the Linux kernel in the Open vSwitch teardown path. The root cause is that after a patch, the teardown code for OVS ports no longer unconditionally takes the RTNL, allowing netdev_destroy() to finish and free the netdev before unregistration completes if the IFF_O...
