CVE-2026-69289.8 CRI

———IBM Concert 1.0.0 through 3.0.0 references or accesses memory after it has been freed. This allows an attacker who can influence program execution or input may exploit this condition to corrupt memory, cause application crashes, or execute arbitrary code.12h CVE-2026-968897.8 HIG

———A flaw was found in librsvg. When processing an SVG document containing nested XML inclusions (Xincludes) with duplicate entity declarations, a use-after-free error can occur. This vulnerability arises because the library incorrectly frees an XML entity that is still in use by the parser. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code.13h CVE-2026-918187.8 HIG

——2A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s JavaScript handling of PDF annotations. Reentrant page-event processing during annotation enumeration may release the associated page object, which is subsequently accessed, resulting in an application crash.15h CVE-2026-918167.8 HIG

——2A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF annotations. Reentrant annotation deletion triggered by embedded JavaScript can cause the application to access an annotation object after it has been released, resulting in a use-after-free condition and application crash.15h CVE-2026-918097.8 HIG

——2A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of malformed PDF form fields. Improper validation during field-name traversal may cause the application to access a released object, resulting in an application crash.15h CVE-2026-918067.8 HIG

——2A use-after-free vulnerability exists in Foxit PDF Editor/Reader’s handling of PDF form fields. Embedded JavaScript may access form-field references after the corresponding fields have been released, resulting in an application crash.15h
