CVE-2026-52984

Summary : Linux kernel net/sched/netem vulnerability fixed by correcting the queue limit check. The netem_enqueue() limit used q->t_len (internal tfifo only) and did not count packets placed in sch->q by the reorder path (__qdisc_enqueue_head), allowing total queue occupancy to exceed sch-&...

CVE-2026-52916

A flaw was found in the Linux kernel's batman-adv module. A remote attacker can exploit this vulnerability by sending specially crafted BATADVUNICASTFRAG packets, which are designed to contain other fragmented packets. This 'fragments in fragments' scenario causes the kernel to recursively proces...

CVE-2026-52912

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfqueue: hold bridge skb-dev while queued brpassframeup rewrites skb-dev from the ingress port to the bridge master before queueing bridge LOCALIN packets. NFQUEUE only holds references on state.in/out and bridge...

CVE-2026-52934 batman-adv: tvlv: reject oversized TVLV packets

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tvlv: reject oversized TVLV packets batadvtvlvcontainerogmappend builds a TVLV packet section from the tvlv.containerlist. The total size of this section is computed by batadvtvlvcontainerlistsize, which sums the size...

CVE-2026-52934

The CVE-2026-52934 entry involves the Linux kernel’s batman-adv TVLV handling. The root cause is batadv_tvlv_container_list_size() using a 16-bit accumulator, which can wrap when the total size exceeds U16_MAX, causing an undersized allocation in batadv_tvlv_container_ogm_append() and a subsequen...

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...
