CVE-2026-52931

In the Linux kernel, the batman-adv TP meter logic could access sender-only fields when tp_vars had the BATADV_TP_RECEIVER role, causing undefined behavior. Specifically, batadv_tp_recv_ack() and batadv_tp_stop() are only valid for BATADV_TP_SENDER; if invoked while in the receiver role (e.g., wh...

CVE-2026-46208

A flaw was found in the Linux kernel's batman-adv module. When a mesh interface is removed, the batadvmeshfree function does not properly stop tpmeter sessions. This oversight allows active tpmeter sender threads or late incoming packets to continue processing against a mesh instance that is in t...

CVE-2026-46208

In the Linux kernel, the following vulnerability has been resolved: batman-adv: stop tpmeter sessions during mesh teardown TP meter sessions remain linked on batpriv-tplist after the netlink request has already finished. When the mesh interface is removed, batadvmeshfree currently tears down the...

CVE-2026-46206

CVE-2026-46206

The CVE-2026-46206 issue affects the Linux kernel’s batman-adv implementation, where the tp_meter component could start new sender or receiver sessions after mesh_state had exited BATADV_MESH_ACTIVE during teardown. The vulnerability stems from improper state management in batman-adv/tp_meter, po...
