Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 462921

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: wifi: mwifiex: fix use-after-free in
 mwifiex_adapter_cleanup() The mwifiex_adapter_cleanup() function uses timer_delete() (non-synchronous) for
 the wakeup_timer before the adapter structure is freed. This is incorrect because timer_delete() does not
 wait for any running timer callback to complete. If the wakeup_timer callback (wakeup_timer_fn) is
 executing when mwifiex_adapter_cleanup() is called, the callback will continue to access adapter fields
 (adapter->hw_status, adapter->if_ops.card_reset, etc.) which may be freed by mwifiex_free_adapter() called
 later in the mwifiex_remove_card() path. Use timer_delete_sync() instead to ensure any running timer
 callback has completed before returning. (CVE-2026-46069)

Solution

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