Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 463832

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: PCI/IOV: Fix race between SR-IOV
 enable/disable and hotplug Commit 05703271c3cd ("PCI/IOV: Add PCI rescan-remove locking when
 enabling/disabling SR-IOV") tried to fix a race between the VF removal inside sriov_del_vfs() and
 concurrent hot unplug by taking the PCI rescan/remove lock in sriov_del_vfs(). Similarly the PCI
 rescan/remove lock was also taken in sriov_add_vfs() to protect addition of VFs. This approach however
 causes deadlock on trying to remove PFs with SR-IOV enabled because PFs disable SR-IOV during removal and
 this removal happens under the PCI rescan/remove lock. So the original fix had to be reverted. Instead of
 taking the PCI rescan/remove lock in sriov_add_vfs() and sriov_del_vfs(), fix the race that occurs with
 SR-IOV enable and disable vs hotplug higher up in the callchain by taking the lock in sriov_numvfs_store()
 before calling into the driver's sriov_configure() callback. (CVE-2025-40219)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
