Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 458166

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/msm/dpu: fix mismatch between
 power and frequency During DPU runtime suspend, calling dev_pm_opp_set_rate(dev, 0) drops the MMCX rail to
 MIN_SVS while the core clock frequency remains at its original (highest) rate. When runtime resume re-
 enables the clock, this may result in a mismatch between the rail voltage and the clock rate. For example,
 in the DPU bind path, the sequence could be: cpu0: dev_sync_state -> rpmhpd_sync_state cpu1:
 dpu_kms_hw_init timeline 0 ------------------------------------------------> t After rpmhpd_sync_state,
 the voltage performance is no longer guaranteed to stay at the highest level. During dpu_kms_hw_init,
 calling dev_pm_opp_set_rate(dev, 0) drops the voltage, causing the MMCX rail to fall to MIN_SVS while the
 core clock is still at its maximum frequency. When the power is re-enabled, only the clock is enabled,
 leading to a situation where the MMCX rail is at MIN_SVS but the core clock is at its highest rate. In
 this state, the rail cannot sustain the clock rate, which may cause instability or system crash. Remove
 the call to dev_pm_opp_set_rate(dev, 0) from dpu_runtime_suspend to ensure the correct vote is restored
 when DPU resumes. Patchwork: https://patchwork.freedesktop.org/patch/710077/ (CVE-2026-53056)

Solution

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