CVE-2026-86143

libxml2 before 2.15.4 has an integer overflow in the xmlIO module. An inconsistency between xmlOutputWriteCallback and xmlBufUse causes negative length values to reach downstream write callbacks when data backlogs exceed maximum integer limits (approximately 2 GiB ). This can lead to data corrupt...

CVE-2026-86139

libxml2 before 2.15.4 contains an integer overflow in the xmlURIEscapeStr function within uri.c. The upstream fix (commit 8edbbdb0) adds a zero-length guard after xmlStrlen to catch cases where the function returns 0 for a non-empty input, preventing the overflow. According to Red Hat, the flaw c...
