Overview
Affected versions of this package are vulnerable to Divide By Zero in the bnxt_qplib_alloc_init_hwq process. An attacker can cause a kernel panic and denial of service by sending a crafted RDMA connection request to a system with the nvme target and use_srq enabled, which triggers a divide-by-zero error in kernel space SRQ creation.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
