  "description": "In the Linux kernel, the following vulnerability has been resolved:  media: mtk-jpeg: Fix use after free bug due to uncanceled work  In mtk_jpeg_probe, \u0026jpeg-\u003Ejob_timeout_work is bound with mtk_jpeg_job_timeout_work. Then mtk_jpeg_dec_device_run and mtk_jpeg_enc_device_run may be called to start the work. If we remove the module which will call mtk_jpeg_remove to make cleanup, there may be a unfinished work. The possible sequence is as follows, which will cause a typical UAF bug.  Fix it by canceling the work before cleanup in the mtk_jpeg_remove  CPU0                  CPU1                      |mtk_jpeg_job_timeout_work mtk_jpeg_remove     |   v4l2_m2m_release  |     kfree(m2m_dev); |                     |                     | v4l2_m2m_get_curr_priv                     |   m2m_dev-\u003Ecurr_ctx //use",
