  "summary": "CVE-2026-85234 is fixed in 3 products on 1 platform, first by RHSA-2026:82280, released September 15, 2026. It is not reported as exploited. Patch Radar priority: High.",
  "title": "tftp-hpa: A flaw was found in tftp-hpa",
  "description": "A flaw was found in tftp-hpa. When the \u0060in.tftpd\u0060 remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the \u0060genmatchstring()\u0060 function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.",
