Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.12.95/6.18.34/7.0.11 and classified as problematic. This vulnerability affects the function remove of the component rockchip. The manipulation of the argument db_clk with an unknown input leads to a allocation of resources vulnerability. The CWE definition for the vulnerability is CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. As an impact it is known to affect integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: teardown bugs and resource leaks Address several teardown issues and resource leaks in the driver's remove path and error handling: 1. Debounce clock reference leak: The debounce clock (bank->db_clk) is obtained using of_clk_get() which increments the clock's reference count, but clk_put() is never called. Register a devm action to cleanly release it on unbind. Note that of_clk_get(..., 1) remains necessary over devm_clk_get() because the DT binding does not define clock-names, precluding name-based lookup. 2. Unregistered chained IRQ handler: The chained IRQ handler is not disconnected in remove(). If a stray interrupt fires after the driver is removed, the kernel attempts to execute a stale handler, leading to a panic. Fix this by clearing the handler in remove(). 3. IRQ domain leak: The linear IRQ domain and its generic chips are allocated manually during probe but never removed. Remove the IRQ domain during driver teardown to free the associated generic chips and mappings. [Bartosz: don't emit an error message on devres allocation failure]

The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2026-64241 since 07/19/2026. The exploitation appears to be easy. The attack needs to be approached locally. Additional levels of successful authentication are required for exploitation. There are known technical details, but no exploit is available.

Upgrading to version 6.12.96, 6.18.35 or 7.0.12 eliminates this vulnerability. Applying the patch cdc603ce3118232712ba443dd8b414d8f25ca467/7f945f7f10f442270518dfd768d230227c495fcf/6be81e77e1748665d7ddab9128ff1d35eb75b87d/9500077678230e36d22bf16d2b9539c13e59a801 is able to eliminate this problem.
