ethernet: aeroflex: fix potential skb leak in greth_init_rings()
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: 0.23% (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 063a932b64db3317ec020c94466fe52923a15f60, 223654e2e2c8d05347cd8e300f8d1ec6023103dd, 87277bdf2c370ab2d07cfe77dfa9b37f82bbe1e5.
Low priority for now. Upgrade to Linux Linux 063a932b64db3317ec020c94466fe52923a15f60, 223654e2e2c8d05347cd8e300f8d1ec6023103dd, 87277bdf2c370ab2d07cfe77dfa9b37f82bbe1e5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: ethernet: aeroflex: fix potential skb leak in greth_init_rings() The greth_init_rings() function won't free the newly allocated skb when dma_mapping_error() returns error, so add dev_kfree_skb() to fix it. Compile tested only.

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.
