Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989840)

medium Nessus Plugin ID 273957

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-2025-989840 advisory.

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

 drm/etnaviv: check for reaped mapping in etnaviv_iommu_unmap_gem

 When the mapping is already reaped the unmap must be a no-op, as we would otherwise try to remove the mapping twice, corrupting the involved data structures.

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.
