CVE-2024-42241

A denial of service vulnerability was found in the Linux Kernel. In architectures such as ARM64 where the base page size is 64KB, a 512MB page cache could lead to a software crash...

CVE-2024-42241

In the Linux kernel, the following vulnerability has been resolved: mm/shmem: disable PMD-sized page cache if needed For shmem files, it's possible that PMD-sized page cache can't be supported by xarray. For example, 512MB page cache on ARM64 when the base page size is 64KB can't be supported by...

CVE-2024-42243 mm/filemap: make MAX_PAGECACHE_ORDER acceptable to xarray

In the Linux kernel, the following vulnerability has been resolved: mm/filemap: make MAXPAGECACHEORDER acceptable to xarray Patch series "mm/filemap: Limit page cache size to that supported by xarray", v2. Currently, xarray can't support arbitrary page cache size. More details can be found from t...

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...

CVE-2024-42241

The CVE-2024-42241 issue affects the Linux kernel’s PMD-sized page cache in shmem files. When the HPAGE_PMD_ORDER exceeds MAX_PAGECACHE_ORDER, PMD-sized page caches may not be supported by xarray, leading to errors like xas_split_alloc, split_huge_page_to_list_to_order, and related fallocate/shme...

CVE-2024-41031

In the Linux kernel, the following vulnerability has been resolved: mm/filemap: skip to create PMD-sized page cache if needed On ARM64, HPAGEPMDORDER is 13 when the base page size is 64KB. The PMD-sized page cache can't be supported by xarray as the following error messages indicate. ------------...
