Unity Linux 20.1070e Security Update: kernel (UTSA-2026-005419)
medium Nessus Plugin ID 300423
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-2026-005419 advisory.In the Linux kernel, the following vulnerability has been resolved:
tls: stop recv() if initial process_rx_list gave us non-DATA
If we have a non-DATA record on the rx_list and another record of the same type still on the queue, we will end up merging them:
- process_rx_list copies the non-DATA record
- we start the loop and process the first available record since it's of the same type
- we break out of the loop since the record was not DATA
Just check the record type and jump to the end in case process_rx_list did some work.
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.See Also
