Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 462998

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: nfc: nci: fix circular locking
dependency in nci_close_device nci_close_device() flushes rx_wq and tx_wq while holding req_lock. This
causes a circular locking dependency because nci_rx_work() running on rx_wq can end up taking req_lock
too: nci_rx_work -> nci_rx_data_packet -> nci_data_exchange_complete -> __sk_destruct -> rawsock_destruct
-> nfc_deactivate_target -> nci_deactivate_target -> nci_request -> mutex_lock(&ndev->req_lock) Move the
flush of rx_wq after req_lock has been released. This should safe (I think) because NCI_UP has already
been cleared and the transport is closed, so the work will see it and return -ENETDOWN. NIPA has been
hitting this running the nci selftest with a debug kernel on roughly 4% of the runs. (CVE-2026-31509)

Solution

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