CVE-2026-97571

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Propagate TPA buffer allocation failures in bnxt_queue_mem_alloc()

bnxt_alloc_one_tpa_info_data() returns -ENOMEM as soon as one allocation
fails. This leaves the remaining rxr->rx_tpa[] entries zeroed.

bnxt_queue_mem_alloc() discards that return value, so the partially
initialized ring is installed by bnxt_queue_start().

Since the agg_id is picked by the hardware and bnxt_alloc_agg_idx maps
it to a SW index in rxr->rx_tpa[], it is possible that an uninitialized
slot can be chosen which would hand a zero DMA address to the device.

Fix this by checking the return value of bnxt_alloc_one_tpa_info_data
and unwinding, freeing the ring buffers.
