Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-371360)

medium Nessus Plugin ID 267628

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-2025-371360 advisory.

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

 uprobes: fix kernel info leak via [uprobes] vma

 xol_add_vma() maps the uninitialized page allocated by __create_xol_area() into userspace. On some architectures (x86) this memory is readable even without VM_READ, VM_EXEC results in the same pgprot_t as VM_EXEC|VM_READ, although this doesn't really matter, debugger can read this memory anyway.

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.
