CVE-2026-97574: bnxt_en: Don't free the live ring's TPA state on queue restart failure
Noroxi assessment
Priority: Monitor (action score 0/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
- Fixed version: Linux Linux 0596a7caa6fc283e142716739099c038d8714082, 5ce7f36c334d723954855ac769ede2fe0e8f89c8, 6.12.112.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to Linux Linux 0596a7caa6fc283e142716739099c038d8714082, 5ce7f36c334d723954855ac769ede2fe0e8f89c8, 6.12.112 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Don't free the live ring's TPA state on queue restart failure bnxt_queue_mem_alloc() shallow copies the live RX ring into the clone: memcpy(clone, rxr, sizeof(*rxr)); the code currently clears pointers that the clone owns (such as rx_agg_bmap), but rx_tpa and rx_tpa_idx_map are left pointing at memory of the live ring that was cloned. If an allocation failure happens later and the err_free_tpa_info label is taken, the live ring's memory can be freed while still in use. Fix this by initializing the clone's pointers to NULL to prevent live ring state from being freed inadvertently.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
