AnalysisCVE.org

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.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
