A flaw was found in the Linux kernel's regulator subsystem. This vulnerability arises from a programming error where a device tree node pointer is released too early, creating a "dangling pointer"—a reference to memory that is no longer valid. This can lead to system instability, potentially causing the system to crash, resulting in a Denial of Service (DoS). In some scenarios, this type of memory corruption could also be exploited by a local attacker to achieve arbitrary code execution.
