Descriptions
In the Linux kernel, the following vulnerability has been resolved:
riscv: Sparse-Memory/vmemmap out-of-bounds fix
Offset vmemmap so that the first page of vmemmap will be mapped
to the first page of physical memory in order to ensure that
vmemmap’s bounds will be respected during
pfn_to_page()/page_to_pfn() operations.
The conversion macros will produce correct SV39/48/57 addresses
for every possible/valid DRAM_BASE inside the physical memory limits.
v2:Address Alex's comments
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: riscv: Sparse-Memory/vmemmap fuera de los límites corrige Offset vmemmap para que la primera página de vmemmap se asigne a la primera página de la memoria física para garantizar que vmemmap Los límites se respetarán durante las operaciones pfn_to_page()/page_to_pfn(). Las macros de conversión producirán direcciones SV39/48/57 correctas para cada DRAM_BASE posible/válida dentro de los límites de la memoria física. v2: Abordar los comentarios de Alex
