n the Linux kernel, the following vulnerability has been resolved: riscv: Fix loading 64-bit NOMMU kernels past the start of RAM commit 3335068f8721 ("riscv: Use PUD/P4D/PGD pages for the linear mapping") added logic to allow using RAM below the kernel load address. However, this does not work for NOMMU, where PAGE_OFFSET is fixed to the kernel load address. Since that range of memory corresponds to PFNs below ARCH_PFN_OFFSET, mm initialization runs off the beginning of mem_map and corrupts adjacent kernel memory. Fix this by restoring the previous behavior for NOMMU kernels.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: riscv: se corrigió la carga de kernels NOMMU de 64 bits después del inicio de la confirmación de RAM. 3335068f8721 ("riscv: use páginas PUD/P4D/PGD para el mapeo lineal") se agregó lógica para permitir el uso RAM debajo de la dirección de carga del kernel. Sin embargo, esto no funciona para NOMMU, donde PAGE_OFFSET está fijado a la dirección de carga del kernel. Dado que ese rango de memoria corresponde a los PFN por debajo de ARCH_PFN_OFFSET, la inicialización de mm se ejecuta desde el principio de mem_map y corrompe la memoria del kernel adyacente. Solucione este problema restaurando el comportamiento anterior de los núcleos NOMMU.
