There is a local root exploit for GPFS commands like mmlsquota, see https://www.ibm.com/support/pages/node/6151701?myns=s033&mynp=OCSTXKQY&mync=E&cm_sp=s033-_-OCSTXKQY-_-E.
As a temporary workaround the setuid-flag has been removed from GPFS commands, disabling regular users from running e.g. mmlsquota. Running mmlsquota now throws a rather misleading error:
That just means, that $USER is not privileged to run the command, not that there is something wrong with GPFS. It will be fixed with the next GPFS update on maxwell.
