kernel: Linux kernel eBPF RINGBUF map oversized allocation

A flaw out of bound memory write in the Linux kernel BPF subsystem was found in the way user writes to BPF ring buffer too fast, so larger buffer than available memory could be allocated. A local user could use this flaw to crash the system or possibly escalate their privileges on the system...
