Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-010839)

low Nessus Plugin ID 308414

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-2026-010839 advisory.

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

acct: fix potential integer overflow in encode_comp_t()

The integer overflow is descripted with following codes:
> 317 static comp_t encode_comp_t(u64 value) > 318 { > 319 int exp, rnd;
......
> 341 exp <<= MANTSIZE;
> 342 exp += value;
> 343 return exp;
> 344 }

Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of 'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535.

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.
