CVE-2026-53299: net: airoha: Move ndesc initialization at end of airoha_qdma_init_tx()

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 90619fdedfb9cc8a80f217d882ee7a84d3703e72, ece31f9dae0c3cd3277e66667e7b8ab2577cf34a, f329924bb49458c65297f1361f545816a5b90998.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 90619fdedfb9cc8a80f217d882ee7a84d3703e72, ece31f9dae0c3cd3277e66667e7b8ab2577cf34a, f329924bb49458c65297f1361f545816a5b90998 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net: airoha: Move ndesc initialization at end of airoha_qdma_init_tx() If queue entry list allocation fails in airoha_qdma_init_tx_queue routine, airoha_qdma_cleanup_tx_queue() will trigger a NULL pointer dereference accessing the queue entry array. The issue is due to the early ndesc initialization in airoha_qdma_init_tx_queue(). Fix the issue moving ndesc initialization at end of airoha_qdma_init_tx routine.

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.

EPSS, last 120 days

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 researchers

Finders, 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.
