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).

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: icssg: guard PA stat lookups icssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name() with FW PA stat names regardless of whether the PA stats block is present on the hardware. emac_get_stat_by_name() already guards the PA stats lookup with `if (emac->prueth->pa_stats)`; when that pointer is NULL the lookup falls through to netdev_err() and returns -EINVAL. Because ndo_get_stats64 is polled regularly by the networking stack this produces thousands of log entries of the form: icssg-prueth icssg1-eth end0: Invalid stats FW_RX_ERROR A secondary consequence is that the int(-EINVAL) return value is implicitly widened to a near-ULLONG_MAX unsigned value when accumulated into the __u64 fields of rtnl_link_stats64, silently corrupting the rx_errors, rx_dropped and tx_dropped counters reported by `ip -s link`. Every other PA-aware code path in the driver is already guarded with the same `if (emac->prueth->pa_stats)` check. Apply the same guard here.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
No commit or PR link among the references.
Credits
All researchersFinders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.
No credits in the CNA record.
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.
