xattr bounds check

The xattr bounds check tag covers discussions about the CVE-2026-46094 vulnerability in the Linux kernel's ext4 filesystem, where a faulty extended-attribute bounds check could allow a four-byte read past the valid xattr region. The fix involves a one-line change in fs/ext4/xattr.c. For Windows users, this vulnerability impacts WSL, Linux VMs, containers, and mixed-OS storage workflows, making patch management a broader concern. The tag focuses on the technical details of the bounds check flaw, its minimal fix, and the implications for enterprise IT environments that rely on ext4 filesystems across Windows and Linux platforms.
