What is CVE-2022-38791?

A local deadlock vulnerability exists in MariaDB versions prior to 10.9.2 due to the compress_write function in the ds_compress.cc file not releasing the data_mutex when a stream write fails. This oversight can allow local users to create a situation where database operations become stuck, leading to a denial of service. It is essential for users of affected versions to apply the necessary updates to mitigate this risk and maintain database integrity.
