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 irdmascceqinit() warn: can subtract underflow 'info->dev->hmcfpmmisc.maxceqs'? 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.
