If registration fails, input_free_device()\nfrees the input device but data->input2 still points to the freed memory.\nalps_input_configured() calls hid_hw_open() before allocating input2, so\nURBs are already active and raw_event can fire during the failure window.\nA U1_SP_ABSOLUTE_REPORT_ID report arriving then causes u1_raw_event()\nto dereference the freed data->input2 -> use-after-free.\n\nFix by only storing input2 into drvdata after successful registration\nand adding a NULL guard in the raw_event path.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/2e55d76e6e8a756f6d87c241de975599f82b02fa","tags":[]},{"url":"https://git.kernel.org/stable/c/443f6b93442b10b972a16f57ceaaea75b77892b6","tags":[]},{"url":"https://git.kernel.org/stable/c/47e5e177e9e4e10da6f2759d5ce8d049e33efdc4","tags":[]},{"url":"https://git.kernel.org/stable/c/5a8ad63158165bacd6a1d7420e0fe5364c913b06","tags":[]},{"url":"https://git.kernel.org/stable/c/64f824dccfd316fd3db8ea1cc4e8a76ad6a02740","tags":[]},{"url":"https://git.kernel.org/stable/c/925da1d2a24787f24872de13a4680437c54de179","tags":[]},{"url":"https://git.kernel.org/stable/c/d3aba3442798ce4a4c8ce3104d7b286d61e605f9","tags":[]},{"url":"https://git.kernel.org/stable/c/ef8ca5bb4c8b9696f38b1bebce1c851baa02b77b","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
