Description

In the Linux kernel, the following vulnerability has been resolved:

ethtool: cmis_cdb: use correct rpl size in ethtool_cmis_module_poll()

rpl is passed as a pointer to ethtool_cmis_module_poll(), so the correct size of rpl is sizeof(*rpl) which should be just 1 byte. Using the pointer size instead can cause stack corruption:
