There is a bug in MySQL 8.0.18, and above https://bugs.mysql.com/bug.php?id=103225 it was patched in 8.0.28 https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-28.html
It looks as though Percona released version 8.0.28, which includes all features and bug fixes in MySQL. However, if you only do security updates, it’s possible you might have an older version of Percona based on your server’s deployment date. You can run
MySQL --version via SSH to confirm.
If you’re not on 8.0.28, then you can run
apt-get update and then
apt-get upgrade. However, this will upgrade all packages on the system. So instead, you might just want to update Percona by running
apt-get install --only-upgrade percona-server-common.
If you’re worried about what
apt-get upgrade will do, you can run it in safe mode and see what packages will be upgraded and their version; simply type
apt-get -V -s upgrade.
As for MariaDB, this was patched in 10.5.7 https://jira.mariadb.org/browse/MDEV-24015 same process applies as above.
