Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-411351)

medium Nessus Plugin ID 267134

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-2025-411351 advisory.

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

 IB/hfi1: Fix a memleak in init_credit_return

 When dma_alloc_coherent fails to allocate dd->cr_base[i].va, init_credit_return should deallocate dd->cr_base and dd->cr_base[i] that allocated before. Or those resources would be never freed and a memleak is triggered.

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.
