CVE-2026-72226
A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module. An integer overflow can occur when calculating the length of a Translation Table Type-Length-Value TVLV unicast message. This overflow can lead to invalid safety checks, allowing an...
CVE-2026-72226
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: prevent TVLV OOB check overflow A TT unicast TVLV contains the number of VLANs stored in it. This number is an u16 and gets multiplied by the size of the struct batadvtvlvttvlandata 8 bytes. The size can therefore...

CVE-2026-72227 batman-adv: mcast: avoid OOB read of num_dests header
In the Linux kernel, the following vulnerability has been resolved: batman-adv: mcast: avoid OOB read of numdests header Before the access to struct batadvtvlvmcasttracker's numdests, it is attempted to check whether enough space is actually in the network header. But instead of using offsetofend...
CVE-2026-72227
CVE-2026-72227 affects the Linux kernel’s Batman- ADV multicast (mcast) handling. The issue occurs when accessing batadv_tvlv_mcast_tracker’s num_dests: instead of validating the full header size with a safe check (offsetofend), the code calls offsetof, which returns 0, causing the network header...

CVE-2026-72226
CVE-2026-72226 concerns the Linux kernel’s batman-adv TT TVLV handling. A unicast TVLV contains the number of VLANs (u16) and multiplies it by 8 (batadv_tvlv_tt_vlan_data). This can overflow the 16-bit tt_vlan_len, invalidating safety checks for out-of-bounds access. The published fix switches to...

CVE-2026-64088
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix negative ttbufflen batadvorignode::ttbufflen was declared as s16, but the field is never intended to hold a negative value. When a value greater than 32767 is assigned, it wraps to a negative signed integer. I...
SUSE CVE-2026-52934
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.

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...
