CVE-2026-63955

The CVE-2026-63955 entry concerns a Linux kernel issue in mm/vmalloc where __get_vm_area_node() would trigger BUG_ON(in_interrupt()) even when BH were disabled. The call path through __vlan_add()/br_fdb_add_local() and rhashtable_lookup_insert_fast() could reach kvmalloc/vmalloc, leading to a BUG...
