drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via crafted packets.

Security readout for executives and security teams

This is an old Linux kernel flaw in the Chelsio cxgb3 InfiniBand/RDMA connection-management code. On affected systems, crafted network packets could trigger a use-after-free, potentially causing a crash or arbitrary code execution. Business risk is concentrated on legacy Linux hosts using the affected driver, not every Linux server. Likely exposure is legacy Linux kernels before 4.5, especially vendor kernels that had not received the relevant 2016 security updates, with Chelsio cxgb3 InfiniBand/RDMA functionality present or enabled. Treat as a focused legacy-infrastructure risk. It does not justify broad emergency action across all Linux systems, but affected RDMA-capable hosts should be patched or isolated because the stated impact includes kernel crash or code execution. Mitigation focus: Apply the relevant vendor kernel security update or a kernel containing the upstream fix.; Prioritize legacy Linux hosts with Chelsio cxgb3 or InfiniBand/RDMA functionality.; Check vendor advisories for supported package versions and backported fixes..
