kernel: mm/filemap: skip to create PMD-sized page cache if needed

A vulnerability was found in the Linux kernel related to how large page caching is handled, particularly for AMD64 architectures. The issue stems from the xarray data structure's inability to support PMD-sized page caches when the base page size is larger than MAXPAGECACHEORDER. The particular...

kernel: 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...

The vulnerability of the lib/xarray.c library in the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the lib/xarray.c library in the Linux operating system’s kernel is related to a memory leak caused by the incorrect use of a function for releasing resources. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: mm: cachestat: fix folio read-after-free in cache walk

In the Linux kernel, the following vulnerability has been resolved: mm: cachestat: fix folio read-after-free in cache walk In cachestat, we access the folio from the page cache's xarray to compute its page offset, and check for its dirty and writeback flags. However, we do not hold a reference to...
