Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/panfrost: Fixed corruption of the shrinker list caused by the madvise IOCTL. Calling the madvise IOCTL twice on BO causes corruption of the memory shrinker list, leading to a kernel crash. This occurs because BO is already on...

kernel: mm/khugepaged: write all dirty file folios when collapsing

A flaw was found in the Linux kernel's memory management mm/khugepaged component. A local user could trigger an edge case where unsaved changes to file data dirty folios are improperly discarded. This occurs when a file with previous writes is subjected to a specific sequence of memory advice...
