Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989055)

high Nessus Plugin ID 273344

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989055 advisory.

In the Linux kernel, the following vulnerability has been resolved:

be2net: Fix buffer overflow in be_get_module_eeprom

be_cmd_read_port_transceiver_data assumes that it is given a buffer that is at least PAGE_DATA_LEN long, or twice that if the module supports SFF 8472. However, this is not always the case.

Fix this by passing the desired offset and length to be_cmd_read_port_transceiver_data so that we only copy the bytes once.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
