CVE-2025-68754

What is CVE-2025-68754?

A vulnerability in the Amlogic RTC driver within the Linux kernel allows for improper resource management due to redundant calls to clk_disable_unprepare(). This can lead to a double free situation when the driver is detached. The fix removes unnecessary manual clock management, trusting the devm framework to handle the lifecycle of the clock correctly and preventing potential memory issues.
