Unity Linux 20.1050e Security Update: kernel (UTSA-2026-007424)

medium Nessus Plugin ID 307085

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-2026-007424 advisory.

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

 amdgpu: validate offset_in_bo of drm_amdgpu_gem_va

 This is motivated by OOB access in amdgpu_vm_update_range when offset_in_bo+map_size overflows.

 v2: keep the validations in amdgpu_vm_bo_map v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map rather than to amdgpu_gem_va_ioctl

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.
