What is known
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.
Business impact
Successful exploitation of CVE-2022-50383, a medium vulnerability (CVSS 5.5) affecting linux kernel, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether linux kernel is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
