Unity Linux 20.1070a Security Update: kernel (UTSA-2025-990347)

medium Nessus Plugin ID 272372

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-2025-990347 advisory.

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

 crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY

 Since commit 8f4f68e788c3 (crypto: pcrypt - Fix hungtask for PADATA_RESET), the pcrypt encryption and decryption operations return
 -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns
 -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.
 Fix this issue by calling crypto layer directly without parallelization in that case.

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.
