CVE-2026-0992 Libxml2: libxml2: denial of service via crafted xml catalogs

A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to...

CVE-2026-0992

CVE-2026-0992 in libxml2 describes an uncontrolled resource consumption vulnerability. A remote attacker can supply crafted XML catalogs containing repeated elements pointing to the same downstream catalog, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU us...

CVE-2026-0989

A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may...
