On 2.10.2 both sites are hardening only:\n       the function is static and its callers pass a freshly emptied buffer,\n       so the overflow that can be reached is the one fixed by the\n       CVE-2025-24928 patch above\n     - CVE-2026-86140\n   * SECURITY UPDATE: NULL pointer dereference in xmlRegNewParserCtxt\n     - debian/patches/libxml2-2.10.2-CVE-2026-86141.patch: compute the\n       expression length only after the xmlStrdup result has been NULL-\n       checked in xmlregexp.c; backport of upstream libxml2 e89a8aae\n       (v2.15.4)\n     - CVE-2026-86141\n   * SECURITY UPDATE: heap buffer overflow in xmlXPtrEvalXPtrPart\n     - debian/patches/libxml2-2.10.2-CVE-2026-86142.patch: check the\n       xpointer part length for overflow before allocating the evaluation\n       buffer in xpointer.c; backport of upstream libxml2 6b3a736c\n       (v2.15.4)\n     - CVE-2026-86142\n   * SECURITY UPDATE: negative lengths reaching output write callbacks\n     - debian/patches/libxml2-2.10.2-CVE-2026-86143.patch: check for int\n       overflow between xmlBufUse and the write callback length in\n       xmlIO.c so a negative length can no longer reach\n       xmlOutputWriteCallback; backport of upstream libxml2 90f293ba\n       (v2.15.4)\n     - CVE-2026-86143\n   * SECURITY UPDATE: XInclude ignores the document parse flags\n     - debian/patches/libxml2-2.10.2-CVE-2026-86144.patch: make\n       xmlXIncludeProcess and xmlXIncludeProcessTree propagate the\n       document's parseFlags (e.g. XML_PARSE_NONET) to the include\n       context in xinclude.c; backport of upstream libxml2 b63cd517\n       (v2.15.4)\n     - Behaviour change: the include context now inherits every parse\n       flag of the document, XML_PARSE_NOENT, XML_PARSE_RECOVER and\n       XML_PARSE_HUGE included, not only XML_PARSE_NONET. A document\n       parsed with XML_PARSE_NOENT and then passed to xmlXIncludeProcess()\n       now also substitutes external entities inside the included\n       documents; callers that must not load them should not pass\n       XML_PARSE_NOENT, or should call xmlXIncludeProcessFlags() with an\n       explicit flag set. PHP's DOMDocument::xinclude() already uses\n       xmlXIncludeProcessFlags() and is unaffected\n     - CVE-2026-86144\n   * Fix deb packaging defects surfaced by the first Debian/Ubuntu build: point the\n     alt-libxml2-devel libxml2.so symlink at the 2.10.2 soname (was 2.9.7) and\n     repair the malformed 2.9.7-2 changelog trailer (three spaces before the date).",
