Details

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->hmcfpmmisc.maxceqs" comes from the firmware in irdmascparsefpmquerybuf() 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.
