CVE-2023-53163: fs/ntfs3: don't hold ni_lock when calling truncate_setsize()

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.15% (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 0226635c304cfd5c9db9b78c259cb713819b057e, 6bb6b1c6b0c31e36736b87a39dd1cbbd9d5ec22f, 73fee7e1e5ea11b51c51c46e0577a197ca3602cf.

Low priority for now. Upgrade to Linux Linux 0226635c304cfd5c9db9b78c259cb713819b057e, 6bb6b1c6b0c31e36736b87a39dd1cbbd9d5ec22f, 73fee7e1e5ea11b51c51c46e0577a197ca3602cf or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: don't hold ni_lock when calling truncate_setsize() syzbot is reporting hung task at do_user_addr_fault() [1], for there is a silent deadlock between PG_locked bit and ni_lock lock. Since filemap_update_page() calls filemap_read_folio() after calling folio_trylock() which will set PG_locked bit, ntfs_truncate() must not call truncate_setsize() which will wait for PG_locked bit to be cleared when holding ni_lock lock.
