Unity Linux 20.1070e Security Update: kernel (UTSA-2026-005462)
medium Nessus Plugin ID 300850
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-2026-005462 advisory.In the Linux kernel, the following vulnerability has been resolved:
nfsd: call op_release, even when op_func returns an error
For ops with trivial replies, nfsd4_encode_operation will shortcut most of the encoding work and skip to just marshalling up the status.
One of the things it skips is calling op_release. This could cause a memory leak in the layoutget codepath if there is an error at an inopportune time.
Have the compound processing engine always call op_release, even when op_func sets an error in op->status. With this change, we also need nfsd4_block_get_device_info_scsi to set the gd_device pointer to NULL on error to avoid a double free.
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.
