Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992323)

medium Nessus Plugin ID 280417

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-2025-992323 advisory.

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

 memstick/ms_block: Fix a memory leak

 'erased_blocks_bitmap' is never freed. As it is allocated at the same time as 'used_blocks_bitmap', it is likely that it should be freed also at the same time.

 Add the corresponding bitmap_free() in msb_data_clear().

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.
