      "title": "HID: winwing: fix use-after-free in force feedback teardown",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: winwing: fix use-after-free in force feedback teardown\n\nwinwing_init_ff() passes the driver's private data, allocated with\ndevm_kzalloc() in winwing_probe(), as the effect context to\ninput_ff_create_memless(). The memoryless force-feedback core takes\nownership of that pointer and frees it with kfree() from\ninput_ff_destroy() (ml_ff_destroy()) when the input device is\ndestroyed.\n\nFreeing a devm-managed allocation with kfree() is an invalid free, and\nthe same object is then released again by devres when the HID device is\ntorn down, a double free. As the allocation also embeds the LED class\ndevices, their timers and work item live on freed memory and the slab\ngets corrupted. This triggers on unbind, rmmod, hot-unplug and on system\nsuspend, where the firmware cache walks the now-corrupt devres list.\nKASAN reports:\n\n  BUG: KASAN: invalid-free in input_ff_destroy\n  Allocated by task N:\n    winwing_probe\n\nPass NULL as the memless context instead and fetch the driver data from\nthe input device in winwing_play_effect(): the HID core already stores\nthe hid_device as the input device's drvdata. The force-feedback core\nthen owns nothing that it must not free.",
