CVE-2026-80838

CVE-2026-80838 affects the vxlan subsystem in the Linux kernel. The root cause is a race condition during a filtered bulk FDB flush: vxlan_fdb_dst_destroy() unlinks the last remote from a non-nexthop FDB entry before the parent entry is removed from the hash table. During this window, an RCU read...
