CVE-2026-3184 3 Kernel, Linux, Redhat 6 Util-linux, Util-linux, Enterprise Linux and 3 more 2026-05-01 3.7 Low
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.
CVE-2026-0992 3 Ibm, Redhat, Xmlsoft 9 Aix, Vios, Enterprise Linux and 6 more 2026-04-22 2.9 Low
A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated <nextCatalog> elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to redundantly traverse catalog chains. This leads to excessive CPU consumption and degrades application availability, resulting in a denial-of-service condition.
CVE-2026-0990 3 Ibm, Redhat, Xmlsoft 9 Aix, Vios, Enterprise Linux and 6 more 2026-04-22 5.9 Medium
A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.
CVE-2026-0989 3 Ibm, Redhat, Xmlsoft 9 Aix, Vios, Enterprise Linux and 6 more 2026-04-22 3.7 Low
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 <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.
