Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 461859

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: rtlwifi: pci: fix possible use-
 after-free caused by unfinished irq_prepare_bcn_tasklet The irq_prepare_bcn_tasklet is initialized in
 rtl_pci_init() and scheduled when RTL_IMR_BCNINT interrupt is triggered by hardware. But it is never
 killed in rtl_pci_deinit(). When the rtlwifi card probe fails or is being detached, the ieee80211_hw is
 deallocated. However, irq_prepare_bcn_tasklet may still be running or pending, leading to use-after-free
 when the freed ieee80211_hw is accessed in _rtl_pci_prepare_bcn_tasklet(). Similar to irq_tasklet, add
 tasklet_kill() in rtl_pci_deinit() to ensure that irq_prepare_bcn_tasklet is properly terminated before
 the ieee80211_hw is released. The issue was identified through static analysis. (CVE-2026-53112)

Solution

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