Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: NFS: Fixed the xarray locking mechanism in nfsnetfsissueread for writeback interrupts. The loop within nfsnetfsissueread currently does not disable interrupts during the iteration of pages in the xarray to perform NFS reads. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: XArray: Fixed the issue with xascreaterange when a multi-index entry is present. If there is already an entry present that is of order = XACHUNKSHIFT when we call xascreaterange, xascreaterange will misinterpret that entry as a...

Astra Linux – Vulnerability in Linux 5.10

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”, version 2. Currently, xarray cannot support arbitrary page cache sizes. More details can be...

Astra Linux – Vulnerability in Linux 5.10

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