This is due to an out of bounds read\nfollowing when `gnutls_record_send()` returns a number of bytes sent **greater\nthan the number of bytes it was given to send**. GnuTLS does that after a\nblocked send.","published":"2026-10-20T21:17:15.000Z","lastModified":"2026-10-22T16:57:53.000Z","status":"Awaiting Analysis","sourceIdentifier":"2499f714-1537-4658-8207-48ae4bb9eae9","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00241,"percentile":0.15061,"date":"2026-10-26","history":[{"date":"2026-10-21","score":0.00259,"percentile":0.16676}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
