  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: i2c: ov7740: fix use-after-destroy in remove\n\nThe ov7740_remove() function had a severe teardown order bug where it\ndestroyed the driver's mutex before freeing the V4L2 control handler\nwhich relies on that mutex, leading to a use-after-destroy kernel panic.\nFurthermore, the driver explicitly called v4l2_ctrl_handler_free() and\nmutex_destroy() sequentially, but then called ov7740_free_controls()\nwhich invokes both of them a second time, resulting in a double-free.\n\nThis patch fixes the issue by unregistering the subdevice first, and\nrelying exclusively on ov7740_free_controls() to safely tear down the\nmutex and control handler in the correct order.",
