CVE-2026-46198

The CVE-2026-46198 issue affects the Linux kernel’s batman-adv component. A mismatch between integer types caused an integer overflow in batadv_iv_ogm_send_to_if, where buff_pos is s16 while the size check uses an int in batadv_iv_ogm_aggr_packet, potentially enabling an out-of-bounds read. The v...
