  3. CVE-2024-56689
In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: epf-mhi: Avoid NULL dereference if DT lacks 'mmio' If platform_get_resource_byname() fails and returns NULL because DT lacks an 'mmio' property for the MHI endpoint, dereferencing res->start will cause a NULL pointer access. Add a check to prevent it. [kwilczynski: error message update per the review feedback] [bhelgaas: commit log]

Summary
  • (es) En el núcleo de Linux, se ha resuelto la siguiente vulnerabilidad: PCI: endpoint: epf-mhi: Evitar la desreferenciación NULL si DT carece de 'mmio' Si platform_get_resource_byname() falla y devuelve NULL porque DT carece de una propiedad 'mmio' para el endpoint MHI, la desreferenciación de res->start provocará un acceso al puntero NULL. Agregue una verificación para evitarlo. [kwilczynski: actualización del mensaje de error según los comentarios de la revisión] [bhelgaas: registro de confirmaciones]
