Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992601)

medium Nessus Plugin ID 280349

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-2025-992601 advisory.

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

 dm crypt: add cond_resched() to dmcrypt_write()

 The loop in dmcrypt_write may be running for unbounded amount of time, thus we need cond_resched() in it.

 This commit fixes the following warning:

 [ 3391.153255][ C12] watchdog: BUG: soft lockup - CPU#12 stuck for 23s! [dmcrypt_write/2:2897] ...

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.
