Echo: linux: security update to 6.1.147-1

medium Tenable Cloud Security Plugin ID 465204

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: vhost-scsi: protect vq->log_used with
 vq->mutex The vhost-scsi completion path may access vq->log_base when vq->log_used is already set to
 false. vhost-thread QEMU-thread vhost_scsi_complete_cmd_work() -> vhost_add_used() -> vhost_add_used_n()
 if (unlikely(vq->log_used)) QEMU disables vq->log_used via VHOST_SET_VRING_ADDR. mutex_lock(&vq->mutex);
 vq->log_used = false now! mutex_unlock(&vq->mutex); QEMU gfree(vq->log_base) log_used() ->
 log_write(vq->log_base) Assuming the VMM is QEMU. The vq->log_base is from QEMU userpace and can be
 reclaimed via gfree(). As a result, this causes invalid memory writes to QEMU userspace. The control queue
 path has the same issue. (CVE-2025-38074)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
