Solution
No solution given by the vendor.
Workaround
To prevent exploitation, restrict access to the `pmstore` utility by configuring the `[access]` section in `/etc/pcp/pmcd/pmcd.conf`. If the `linux_sockets` PMDA is not essential, it can be unloaded or disabled to remove the attack vector. After modifying `pmcd.conf`, the `pmcd` service must be restarted for changes to take effect.
