Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 464071

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: Bluetooth: l2cap: Add missing chan
lock in l2cap_ecred_reconf_rsp l2cap_ecred_reconf_rsp() calls l2cap_chan_del() without holding
l2cap_chan_lock(). Every other l2cap_chan_del() caller in the file acquires the lock first. A remote BLE
device can send a crafted L2CAP ECRED reconfiguration response to corrupt the channel list while another
thread is iterating it. Add l2cap_chan_hold() and l2cap_chan_lock() before l2cap_chan_del(), and
l2cap_chan_unlock() and l2cap_chan_put() after, matching the pattern used in l2cap_ecred_conn_rsp() and
l2cap_conn_del(). (CVE-2026-53071)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
