Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989337)
medium Nessus Plugin ID 273759
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-2025-989337 advisory.In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix call trace in setup_tx_descriptors
After PF reset and ethtool -t there was call trace in dmesg sometimes leading to panic. When there was some time, around 5 seconds, between reset and test there were no errors.
Problem was that pf reset calls i40e_vsi_close in prep_for_reset and ethtool -t calls i40e_vsi_close in diag_test. If there was not enough time between those commands the second i40e_vsi_close starts before previous i40e_vsi_close was done which leads to crash.
Add check to diag_test if pf is in reset and don't start offline tests if it is true.
Add netif_info(testing failed) into unhappy path of i40e_diag_test()
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
