CVE-2022-50383 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Can't set dst buffer to done when lat decode error Core thread will call v4l2_m2m_buf_done to set dst buffer done for lat architecture. If lat call v4l2_m2m_buf_done_and_job_finish to free dst buffer when lat decode error, core thread will access kernel NULL pointer dereference, then crash.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
