Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue concerns the exfat component of the Linux kernel, where a new buffer was not zeroed before writing. This could lead to uninitialized data in the page cache being written. The...

kernel: mm/shmem: disable PMD-sized page cache if needed

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...

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 f2fs component of the Linux operating system’s kernel, which allows a hacker to cause a service failure

The vulnerability of the f2fs component of the Linux operating system’s kernel is related to damage to the f2fsinitpagearraycache function. Exploiting this vulnerability can allow an attacker to access confidential information...
