In the Linux kernel, the following vulnerability has been resolved:
batman-adv: tp_meter: avoid use of uninit sender vars
batadv_tp_recv_ack() and batadv_tp_stop() are only valid for tp_vars in the
BATADV_TP_SENDER role. When called with a BATADV_TP_RECEIVER role, it
proceeds to read sender-only members that were never initialized, leading
to undefined behavior.
This can be triggered when a node that is currently acting as a receiver in
an ongoing tp_meter session receives a malicious ACK packet.
Guard against this by checking tp_vars->role immediately after the
lookup and bailing out if it is not BATADV_TP_SENDER, before any of
those members are accessed.

CVE-2026-52931 CWE-824 kernel: batman-adv: tp_meter: avoid use of uninit sender vars
kernel: batman-adv: tp_meter: avoid use of uninit sender vars
A flaw was found in the `batman-adv` `tp_meter` module of the Linux kernel. A remote attacker could exploit this vulnerability by sending a specially crafted acknowledgment (ACK) packet to a node configured as a receiver in an ongoing `tp_meter` session. This could lead to the use of uninitialized sender variables, resulting in undefined behavior and potentially a denial of service.

In the Linux kernel, the following vulnerability has been resolved:
batman-adv: tp_meter: avoid use of uninit sender vars
batadv_tp_recv_ack() and batadv_tp_stop() are only valid for tp_vars in the
BATADV_TP_SENDER role. When called with a BATADV_TP_RECEIVER role, it
proceeds to read sender-only members that were never initialized, leading
to undefined behavior.
This can be triggered when a node that is currently acting as a receiver in
an ongoing tp_meter session receives a malicious ACK packet.
Guard against this by checking tp_vars->role immediately after the
lookup and bailing out if it is not BATADV_TP_SENDER, before any of
those members are accessed.
No detection rules found.
