CVE-2026-23084

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> be2net: Fix NULL pointer dereference in be_cmd_get_mac_from_list<br /> <br /> When the parameter pmac_id_valid argument of be_cmd_get_mac_from_list() is<br /> set to false, the driver may request the PMAC_ID from the firmware of the<br /> network card, and this function will store that PMAC_ID at the provided<br /> address pmac_id. This is the contract of this function.<br /> <br /> However, there is a location within the driver where both<br /> pmac_id_valid == false and pmac_id == NULL are being passed. This could<br /> result in dereferencing a NULL pointer.<br /> <br /> To resolve this issue, it is necessary to pass the address of a stub<br /> variable to the function.
