Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-151099)

critical Nessus Plugin ID 378360

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-2026-151099 advisory.

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

 ntfs: verify run length exceeding volume boundary

 The mapping pairs decoder validates that the starting LCN is within the volume but does not check if the run extends beyond the volume boundary.

 A malformed NTFS image with a crafted mapping pairs array could cause the kernel to access memory beyond the volume boundary, potentially leading to memory corruption and privilege escalation.

 Add validation to ensure lcn + length stays within nr_clusters.

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.
