Nothing cancels this work\nbefore iio_trig_release() frees the trigger, so a worker armed by the\nlast in-flight IRQ can outlive the free and touch freed memory.\n\nCancel it at the top of iio_trig_release(), which every free path\nreaches through the device core's final put_device().\n\nFound by an in-house static analysis tool.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/2a57b9246cecd5dd797a42eb310d6c8816f26d9e","tags":[]},{"url":"https://git.kernel.org/stable/c/882d0011c59ff8ac15188ec9ce071399ecfa10ad","tags":[]},{"url":"https://git.kernel.org/stable/c/cf513df1a2c75566cdc802d9da47f62e8d6cfd18","tags":[]},{"url":"https://git.kernel.org/stable/c/e64703280ce7a23a43c27efebeb7da457c88bf5c","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
