- Summary
- libxml2: Fix of 4 CVEs
- Details
-
- CVE-2026-86140: add the missing bounds checks around the two unguarded strcat() calls in xmlSnprintfElements(), the sibling of the function fixed for CVE-2025-24928
- CVE-2026-86142: reject a saturated xmlStrlen() result in xmlXPtrEvalXPtrPart() before it is used to size the XPointer buffer
- CVE-2026-86143: check the xmlBufUse() length against INT_MAX before narrowing it to the int parameter of the output writecallback, at all six call sites
- CVE-2026-86144: propagate the document parseFlags through xmlXIncludeProcess(), xmlXIncludeProcessTree() and xmlXIncludeLoadTxt() so XML_PARSE_NONET is honoured during XInclude resolution
