CVE-2026-90147

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. [1]: https://lore.kernel.org/rust-for-linux/20260706-clk-type-state-v5-3-67c5f326a16c@collabora.com
