Unity Linux 20.1050a Security Update: kernel (UTSA-2026-098843)

high Nessus Plugin ID 340493

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-2026-098843 advisory.

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

scsi: ufs: core: Fix handling of lrbp->cmd

ufshcd_queuecommand() may be called two times in a row for a SCSI command before it is completed. Hence make the following changes:

- In the functions that submit a command, do not check the old value of lrbp->cmd nor clear lrbp->cmd in error paths.

- In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.

See also scsi_send_eh_cmnd().

This commit prevents that the following appears if a command times out:

WARNING: at drivers/ufs/core/ufshcd.c:2965 ufshcd_queuecommand+0x6f8/0x9a8 Call trace:
ufshcd_queuecommand+0x6f8/0x9a8 scsi_send_eh_cmnd+0x2c0/0x960 scsi_eh_test_devices+0x100/0x314 scsi_eh_ready_devs+0xd90/0x114c scsi_error_handler+0x2b4/0xb70 kthread+0x16c/0x1e0

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.
