Echo: linux: security update to 6.12.73-1

medium Tenable Self-Hosted Container Security Plugin ID 463427

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: drm/amd/pm: Disable MMIO access during
 SMU Mode 1 reset During Mode 1 reset, the ASIC undergoes a reset cycle and becomes temporarily
 inaccessible via PCIe. Any attempt to access MMIO registers during this window (e.g., from interrupt
 handlers or other driver threads) can result in uncompleted PCIe transactions, leading to NMI panics or
 system hangs. To prevent this, set the `no_hw_access` flag to true immediately after triggering the reset.
 This signals other driver components to skip register accesses while the device is offline. A memory
 barrier `smp_mb()` is added to ensure the flag update is globally visible to all cores before the driver
 enters the sleep/wait state. (cherry picked from commit 7edb503fe4b6d67f47d8bb0dfafb8e699bb0f8a4)
 (CVE-2026-23213)

Solution

Update the linux library and its related packages to version 6.12.73-1 or later.
