CVE-2023-52640: fs/ntfs3: Fix oob in ntfs_listxattr

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0830c5cf19bdec50d0ede4755ddc463663deb21c, 52fff5799e3d1b5803ecd2f5f19c13c65f4f7b23, 6ed6cdbe88334ca3430c5aee7754dc4597498dfb.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0830c5cf19bdec50d0ede4755ddc463663deb21c, 52fff5799e3d1b5803ecd2f5f19c13c65f4f7b23, 6ed6cdbe88334ca3430c5aee7754dc4597498dfb or later.
