Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ntfs: check overflow when iterating ATTRRECORDs The kernel iterates over ATTRRECORDS in mft records in the ntfsattrfind function. Since ATTRRECORDS are adjacent to each other, the kernel can access the next ATTRRECORD from the en...

CVE-2026-42305 Dulwich has an arbitrary file write via NTFS-hostile tree entries on Windows

Dulwich is a pure-Python implementation of the Git file formats and protocols. Versions starting with 0.10.0 and prior to 1.2.5 have an arbitrary file write leading to remote code execution when cloning or checking out a malicious Git repository on Windows.
