Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 457649

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: rawsock: cancel tx_work before
 socket teardown In rawsock_release(), cancel any pending tx_work and purge the write queue before
 orphaning the socket. rawsock_tx_work runs on the system workqueue and calls nfc_data_exchange which
 dereferences the NCI device. Without synchronization, tx_work can race with socket and device teardown
 when a process is killed (e.g. by SIGKILL), leading to use-after-free or leaked references. Set
 SEND_SHUTDOWN first so that if tx_work is already running it will see the flag and skip transmitting, then
 use cancel_work_sync to wait for any in-progress execution to finish, and finally purge any remaining
 queued skbs. (CVE-2026-23372)

Solution

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