Description
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Prevent some integer underflows
My static checker complains that:
drivers/infiniband/hw/irdma/ctrl.c:3605 irdma_sc_ceq_init()
warn: can subtract underflow 'info->dev->hmc_fpm_misc.max_ceqs'?
It appears that "info->dev->hmc_fpm_misc.max_ceqs" comes from the firmware
in irdma_sc_parse_fpm_query_buf() so, yes, there is a chance that it could
be zero. Even if we trust the firmware, it's easy enough to change the
condition just as a hardenning measure.
