Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： clk: devres: 修复 中的清理逻辑 在设置时钟速率之前注册了其清理（cleanup）动作。如果设置速率失败，它会尝试去禁用和取消准备一个实际上从未被启用的时钟。该问题是在审查补丁系列 “rust: clk: add devres-managed clks” [1] 时发现的。 修复方案： 仅当成功准备（prepare）和启用（enable）时钟后，再注册清理动作。 [1]: https://lore.kernel.org/rust-for-linux/202607

Vulnerability Title
clk: devres: fix cleanup in devm_clk_get_optional_enabled_with_rate()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
clk: devres: fix cleanup in devm_clk_get_optional_enabled_with_rate()
devm_clk_get_optional_enabled_with_rate() registers its cleanup action
before setting the clock rate. If setting the rate fails, it attempts to
disable and unprepare a clock that was never enabled. This issue was
spotted while reviewing "rust: clk: add devres-managed clks" [1].
Register the cleanup action only after successfully preparing and enabling
the clock.
