Bug ID: 2043
Summary: ml/cnxk mvtvm: max_nb_qpairs parsed four bytes wide
Product: DPDK
Version: 26.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
drivers/ml/cnxk/mvtvm_ml_dev.c
parse_uint_arg() stores a uint32_t:
*((uint32_t *)extra_args) = i;
but max_nb_qpairs is a uint16_t followed by an int in the same struct, so
parsing that argument writes past the field into its neighbour.
Fixes: 48c6081ab4b3 ("ml/cnxk: enable creation of MVTVM virtual device")
