Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-993258)

medium Nessus Plugin ID 281056

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-2025-993258 advisory.

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

 RDMA/hfi1: fix potential memory leak in setup_base_ctxt()

 setup_base_ctxt() allocates a memory chunk for uctxt->groups with hfi1_alloc_ctxt_rcv_groups(). When init_user_ctxt() fails, uctxt->groups is not released, which will lead to a memory leak.

 We should release the uctxt->groups with hfi1_free_ctxt_rcv_groups() when init_user_ctxt() fails.

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.
