  "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 \u0027info-\u003Edev-\u003Ehmc_fpm_misc.max_ceqs\u0027?  It appears that \u0022info-\u003Edev-\u003Ehmc_fpm_misc.max_ceqs\u0022 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\u0027s easy enough to change the condition just as a hardenning measure.",
