概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- 已解決 Linux 核心中的下列弱點：coresight: cti: Fix hang in cti_disable_hw() cti_enable_hw() and cti_disable_hw() are called from an atomic context so shouldn't use runtime PM because it can result in a sleep when communicating with firmware. Since commit 3c6656337852 (Revert firmware: arm_scmi: Add clock management to the SCMI power domain), this causes a hang on Juno when running the Perf Coresight tests or running this command: perf record -e cs_etm//u -- ls This was also missed until the revert commit because pm_runtime_put() was called with the wrong device until commit 692c9a499b28 (coresight: cti: Correct the parameter for pm_runtime_put) With lock and scheduler debugging enabled the following is output: coresight cti_sys0: cti_enable_hw -- dev:cti_sys0 parent:
