CVE-2026-63834

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: restrict number of unacked list entries When the unackedlist is unbound, an attacker could send messages with small lengths and appropriated seqno + gaps to force the receiver to allocate more and more...

CVE-2026-63836

The CVE-2026-63836 issue is in batman-adv tp_meter within the Linux kernel, caused by a 32-bit arithmetic overflow in batadv_tp_update_cwnd() that can yield a divide-by-zero when cwnd reaches 0x20000000. The correct calculation should be (mss ** 2) * 8 / cwnd to avoid overflow, preserving the 8x ...

CVE-2026-63836 batman-adv: tp_meter: avoid divide-by-zero for dec_cwnd

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: avoid divide-by-zero for deccwnd The cwnd is always MSS = cwnd = 0x20000000. But the calculation in batadvtpupdatecwnd assumes unsigned 32 bit arithmetics. mss 8 2 / cwnd 8 In case cwnd is actually 0x20000000...

CVE-2026-63834

The CVE concerns the Linux kernel’s batman-adv tp_meter: unacked_list can be pressured to grow (via crafted small messages, seqno gaps) if the list is unbounded. The result is potential out-of-memory or high CPU usage from scanning a large unacked_list. If a limit is applied, the implementation m...

CVE-2026-52931

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: avoid use of uninit sender vars batadvtprecvack and batadvtpstop are only valid for tpvars in the BATADVTPSENDER role.

CVE-2026-52931

CVE-2026-52931 — Linux kernel (batman-adv tp_meter): The vulnerability arises when batadv_tp_recv_ack() or batadv_tp_stop() are invoked with a tp_vars in the BATADV_TP_RECEIVER role. In that case, code paths access sender-only members that were never initialized, causing undefined behavior. The f...
