CVE-2026-23160: octeon_ep: Fix memory leak in octep_device_setup()

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: 0.13% (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 5058d3f8f17202e673f90af1446252322bd0850f, 8016dc5ee19a77678c264f8ba368b1e873fa705b, d753f3c3f9d7a6e6dbb4d3a97b73007d71624551.

Low priority for now. Upgrade to Linux Linux 5058d3f8f17202e673f90af1446252322bd0850f, 8016dc5ee19a77678c264f8ba368b1e873fa705b, d753f3c3f9d7a6e6dbb4d3a97b73007d71624551 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: octeon_ep: Fix memory leak in octep_device_setup() In octep_device_setup(), if octep_ctrl_net_init() fails, the function returns directly without unmapping the mapped resources and freeing the allocated configuration memory. Fix this by jumping to the unsupported_dev label, which performs the necessary cleanup. This aligns with the error handling logic of other paths in this function. Compile tested only. Issue found using a prototype static analysis tool and code review.

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.

No history yet (it accumulates with the daily EPSS job).

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.
