The vulnerability allows a local user to perform a denial of service attack (DoS) on the target system.

The vulnerability exists due to double-locking error in the extra/mariabackup/ds_compress.cc. A local user can exploit this vulnerability to cause a deadlock, resulting in a denial of service condition.
