Unity Linux 20.1050e Security Update: kernel (UTSA-2026-007415)

low Nessus Plugin ID 307293

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-2026-007415 advisory.

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

 btrfs: send: handle path ref underflow in header iterate_inode_ref()

 Change BUG_ON to proper error handling if building the path buffer fails. The pointers are not printed so we don't accidentally leak kernel addresses.

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.
