Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002047)

high Nessus Plugin ID 286550

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-2026-002047 advisory.

The evm_update_evmxattr function in security/integrity/evm/evm_crypto.c in the Linux kernel before 3.7.5, when the Extended Verification Module (EVM) is enabled, allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an attempted removexattr operation on an inode of a sockfs filesystem.

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.
