CVE-2026-64090

CVE-2026-64090 affects the Linux kernel’s batman-adv translation table (TT) handling. The issue arises when a TT reply can be generated either directly or via the global TT state, leading to potential inconsistency and the sending of empty VLANs, which can trigger TT request storms and network in...

CVE-2026-64090 batman-adv: tt: avoid empty VLAN responses

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: avoid empty VLAN responses The commit 16116dac2339 "batman-adv: prevent TT request storms by not sending inconsistent TT TLVLs" added checks to the local direct TT response code. But the response can also be done...

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...
