  "description": "In the Linux kernel, the following vulnerability has been resolved:  auxdisplay: hd44780: Fix potential memory leak in hd44780_remove()  hd44780_probe() allocates a memory chunk for hd with kzalloc() and makes \u0022lcd-\u003Edrvdata-\u003Ehd44780\u0022 point to it. When we call hd44780_remove(), we should release all relevant memory and resource. But \u0022lcd-\u003Edrvdata -\u003Ehd44780\u0022 is not released, which will lead to a memory leak.  We should release the \u0022lcd-\u003Edrvdata-\u003Ehd44780\u0022 in hd44780_remove() to fix the memory leak bug.",
