• •Exploitation requires local low-privileged code execution.
• •Linux has released patches to mitigate these vulnerabilities.

Four vulnerabilities affecting the Linux Kernel's NTFS3 file system have been disclosed, allowing local attackers to disclose sensitive information or execute arbitrary code. The vulnerabilities require low-privileged code execution for exploitation. The flaws include issues with directory index entries, directory headers, extended attributes, and NTFS3 journal log records, all stemming from improper validation of user-supplied data. The vulnerabilities can lead to reading past allocated arrays or writing past allocated buffers, potentially enabling attackers to escalate privileges. Linux has issued updates to address these vulnerabilities. The advisories were publicly released on September 14, 2026, following a report to the vendor on June 10, 2026. Security professionals are urged to apply the patches promptly.
