CVE-2025-58145

[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] There are two issues related to the mapping of pages belonging to other domains: For one, an assertion is wrong there, where the case actually needs handling. A NULL pointer de-reference could result on a release build. This is CVE-2025-58144. And then the P2M lock isn't held until a page reference was actually obtained (or the attempt to do so has failed). Otherwise the page can not only change type, but even ownership in between, thus allowing domain boundaries to be violated. This is CVE-2025-58145.

Summary		(es) [Este registro de información de la CNA se relaciona con múltiples CVE; el texto explica qué aspectos/vulnerabilidades corresponden a qué CVE.] Hay dos problemas relacionados con el mapeo de páginas pertenecientes a otros dominios: Por un lado, una aserción es incorrecta allí, donde el caso realmente necesita ser manejado. Una desreferencia de puntero NULL podría resultar en una compilación de lanzamiento. Esto es CVE-2025-58144. Y luego el bloqueo P2M no se mantiene hasta que se obtuvo realmente una referencia de página (o el intento de hacerlo ha fallado). De lo contrario, la página no solo puede cambiar de tipo, sino incluso de propiedad entretanto, permitiendo así que se violen los límites del dominio. Esto es CVE-2025-58145.
