CVE-2026-52934

A flaw was found in the Linux kernel's batman-adv (Better Approach To Mobile Ad-hoc Networking - Advanced) module. An integer overflow vulnerability in the TVLV (Type-Length-Value) packet processing can lead to an undersized memory allocation. This allows a subsequent operation to write beyond the intended buffer, causing kernel memory corruption. This issue could potentially be exploited by an attacker to achieve a denial of service or, in some cases, arbitrary code execution.
