CVE-2024-42243

CVE-2024-42243 relates to the Linux kernel mm/filemap MAX_PAGECACHE_ORDER handling. The issue arises because xarray cannot support arbitrary page cache sizes, triggering WARN_ON in xas_split_alloc on ARM64 when base page size is 64KB (huge pages can be 512MB). The fix implemented patches to LIMIT...
