CVE-2025-40264
UnknownSummary
W jądrze systemu Linux zidentyfikowano podatność w module be2net, która polega na przekazywaniu argumentu wrb_params jako NULL w funkcji be_insert_vlan_in_pkt(). Może to prowadzić do dereferencji wskaźnika NULL podczas przetwarzania specyficznego pakietu.
Risk Assessment
Podatność ta może prowadzić do awarii systemu lub nieprzewidzianego zachowania, co stwarza ryzyko dla stabilności i bezpieczeństwa systemu operacyjnego.
Recommendation
Zaleca się aktualizację jądra systemu Linux do najnowszej wersji, aby usunąć tę podatność oraz zapewnić prawidłowe przekazywanie argumentów w funkcji be_xmit().

This issue can be chained with CVE-2026-61834, potentially leading to remote code execution.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: be2net: pass wrb_params in case of OS2BMC be_insert_vlan_in_pkt() is called with the wrb_params argument being NULL at be_send_pkt_to_bmc() call site. This may lead to dereferencing a NULL pointer when processing a workaround for specific packet, as commit bc0c3405abbb ("be2net: fix a Tx stall bug caused by a specific ipv6 packet") states. The correct way would be to pass the wrb_params from be_xmit().
