CVE-2021-47623

CVE-2021-47623 affects the PowerPC path in the Linux kernel where unmapping a fixmap entry via __set_fixmap() (FIXMAP_PAGE_CLEAR) ends up calling map_kernel_page(), which fails if invoked a second time for the same page. The connected documents confirm the root cause in arch/powerpc/mm/pgtable.c ...
