CVE-2025-40264
be2net: pass wrb_params in case of OS2BMC
Description
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().
