Unity Linux 20.1070e Security Update: kernel (UTSA-2026-013162)

medium Nessus Plugin ID 307963

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-2026-013162 advisory.

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

 Revert mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K

 The commit 8396c793ffdf (mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K) increased the max_req_size, even for 4K pages, causing various issues:
 - Panic booting the kernel/rootfs from an SD card on Rockchip RK3566
 - Panic booting the kernel/rootfs from an SD card on StarFive JH7100
 - swiotlb buffer is full and data corruption on StarFive JH7110

 At this stage no fix have been found, so it's probably better to just revert the change.

 This reverts commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890.

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.
