Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 463552

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: net: mana: fix use-after-free in
 mana_hwc_destroy_channel() by reordering teardown A potential race condition exists in
 mana_hwc_destroy_channel() where hwc->caller_ctx is freed before the HWC's Completion Queue (CQ) and Event
 Queue (EQ) are destroyed. This allows an in-flight CQ interrupt handler to dereference freed memory,
 leading to a use-after-free or NULL pointer dereference in mana_hwc_handle_resp(). mana_smc_teardown_hwc()
 signals the hardware to stop but does not synchronize against IRQ handlers already executing on other
 CPUs. The IRQ synchronization only happens in mana_hwc_destroy_cq() via mana_gd_destroy_eq() ->
 mana_gd_deregister_irq(). Since this runs after kfree(hwc->caller_ctx), a concurrent
 mana_hwc_rx_event_handler() can dereference freed caller_ctx (and rxq->msg_buf) in mana_hwc_handle_resp().
 Fix this by reordering teardown to reverse-of-creation order: destroy the TX/RX work queues and CQ/EQ
 before freeing hwc->caller_ctx. This ensures all in-flight interrupt handlers complete before the memory
 they access is freed. (CVE-2026-23454)

Solution

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