Linux bnxt_re RoCE driver (chip context memory leak): Memory leak in the Broadcom RoCE driver when doorbell BAR mapping
CVE-2024-50172Firmware, BMC & network fabriccurated
Impact
Memory leak in the Broadcom RoCE driver when doorbell BAR mapping fails. Low severity on its own, but doorbell-BAR mapping is the mechanism that gives a userspace RDMA process direct hardware access, and leaks in its error path are worth tracking on a fabric where that mapping is the tenant boundary.
Who can reach it
Local, via repeated RDMA device setup failures.
What to do
Kernel/driver upgrade plus host reboot; bundle with the other bnxt_re fixes rather than scheduling separately.
