Upgrade Oracle:7 python-perf to version 0:3.10.0-1062.el7 or higher.
This issue was patched in ELSA-2019-2029.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-perf package and not the python-perf package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
A flaw was found in the Linux kernel that allows the userspace to call memcpy_fromiovecend() and similar functions with a zero offset and buffer length which causes the read beyond the buffer boundaries, in certain cases causing a memory access fault and a system halt by accessing invalid memory address. This issue only affects kernel version 3.10.x as shipped with Red Hat Enterprise Linux 7.
