Unity Linux 20.1050e Security Update: kernel (UTSA-2026-006622)

medium Nessus Plugin ID 305323

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-2026-006622 advisory.

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

RDMA/qedr: Fix potential memory leak in __qedr_alloc_mr()

__qedr_alloc_mr() allocates a memory chunk for mr->info.pbl_table with init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, mr is released while mr->info.pbl_table is not released, which will lead to a memory leak.

We should release the mr->info.pbl_table with qedr_free_pbl() when error occurs to fix the memory leak.

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.
