CVE-2024-56677

Summary (CVE-2024-56677): In the Linux kernel, the fadump CMA reservation logic for PowerPC was moved to run after initmem_init to fix an early init alignment issue. The root cause was that CMA_MIN_ALIGNMENT_BYTES could be as small as PAGE_SIZE during early boot because pageblock_order is not yet...

CVE-2024-56677

In the Linux kernel, the following vulnerability has been resolved: powerpc/fadump: Move fadumpcmainit to setuparch after initmeminit During early init CMAMINALIGNMENTBYTES can be PAGESIZE, since pageblockorder is still zero and it gets initialized later during initmeminit e.g. setuparch -...
