Description
A flaw was found in the Linux kernel's GPIO (General Purpose Input/Output) subsystem. When an operation setting multiple GPIO values encounters an error, the function exits early without releasing previously allocated memory buffers. A local user could trigger this error condition to cause a memory leak, potentially leading to system resource exhaustion and a Denial of Service (DoS).
