    "summary": "In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8192: Check runtime resume during probe The MT8192 AFE probe enables runtime PM temporarily while reinitializing the regmap cache from hardware, but it uses pm_runtime_get_sync() without checking the return value. If runtime resume fails, probe keeps going without the device necessarily being accessible, and pm_runtime_get_sync() may leave the PM usage count incremented. The regmap_reinit_cache() failure path also returns before dropping the temporary PM reference and before clearing pm_runtime_bypass_reg_ctl. Use pm_runtime_resume_and_get() so resume failures do not leak a usage count, and clear the temporary bypass flag after dropping the probe PM reference on all regmap_reinit_cache() outcomes.",
