Unity Linux 20.1070e Security Update: kernel (UTSA-2025-989693)

high Nessus Plugin ID 272937

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-2025-989693 advisory.

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

f2fs: avoid format-overflow warning

With gcc and W=1 option, there's a warning like this:

fs/f2fs/compress.c: In function f2fs_init_page_array_cache:
fs/f2fs/compress.c:1984:47: error: %u directive writing between 1 and 7 bytes into a region of size between 5 and 8 [-Werror=format-overflow=] 1984 | sprintf(slab_name, f2fs_page_array_entry-%u:%u, MAJOR(dev), MINOR(dev));
| ^~

String f2fs_page_array_entry-%u:%u can up to 35. The first %u can up to 4 and the second %u can up to 7, so total size is 24 + 4 + 7 = 35.
slab_name's size should be 35 rather than 32.

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.
