When the application enables segmentation (via chan_ops.alloc_buf) and the chosen RX pool has a user_data_size smaller than 2 bytes, the segmentation counter stored in the net_buf user_data area is written out of bounds in l2cap_chan_le_recv_seg (subsys/bluetooth/host/l2cap.c). The observed effects are an AddressSanitizer abort and, without ASan, heap corruption /"},"products":[{"@id":"cpe:2.3:a:zephyrproject-rtos:zephyr:*:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:zephyrproject-rtos:zephyr:*:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-09T13:10:47.215Z"}]}
