CVE-2026-53056

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A mismatch between power and frequency occurs during DPU runtime suspend. Calling the function dev pm opp set rate(dev, 0) drops the MMCX rail to MIN SVS while the core clock frequency remains at its highest rate. Upon runtime resume, only the clock is re-enabled, leaving the MMCX rail at MIN SVS while the core clock is at its maximum frequency. Because the rail cannot sustain this clock rate, the system may experience instability or crash.

Recommendations Remove the call to the dev pm opp set rate(dev, 0) function from dpu runtime suspend to ensure the correct vote is restored when the DPU resumes.
