[gpfsug-discuss] kernel 3.10.0-1160.36.2.el7.x86_64 (CVE-2021-33909) not compatible with DB2 (for TSM, HPSS, possibly other IBM apps)

Alert related to sysadmins managing TSM/DB2 servers and those responsible for applying security patches, in particular kernel 3.10.0-1160.36.2.el7.x86_64, despite security concerns raised by CVE-2021-33909:

Please hold off on upgrading your RedHat systems (possibly centos too). I just found out the hard way that kernel 3.10.0-1160.36.2.el7.x86_64 is not compatible with DB2, and after the node reboot DB2 would not work anymore, not only on TSM, but neither on HPSS. I had to revert the kernel to 3.10.0-1062.18.1.el7.x86_64 to get DB2 working properly again.
