CVE-2026-72229

Summary: CVE-2026-72229 relates to the Linux kernel’s batman-adv handling of mesh interfaces. When registering a mesh interface, an untagged struct batadv_meshif_vlan is created on top of the netdev via NETDEV_REGISTER. If another notifier vetoes the registration, netdev registration is aborted a...

CVE-2026-68301 net: hsr: fix memory leak on slave unregistration by removing synced VLANs

In the Linux kernel, the following vulnerability has been resolved: net: hsr: fix memory leak on slave unregistration by removing synced VLANs When an HSR master device is brought UP, it auto-adds VLAN 0 via vlanvid0add, which propagates VID 0 to its slave devices slave A and B. If a slave device...

CVE-2025-37864

CVE-2025-37864 relates to the Linux kernel DSA subsystem: a cleanup path for FDB, MDB and VLAN entries on unbind was added to fix a scenario where bridge bypass operations could leave stale entries and trigger a leak/warn on unbind. The vulnerability stems from the assumption that higher layers b...
