CVE-2024-41016: ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()

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: 0.24% (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 57a3d89831fcaa2cdbe024b47c7c36d5a56c3637, af77c4fc1871847b528d58b7fdafb4aa1f6a9262, c031d286eceb82f72f8623b7f4abd2aa491bfb5e.
  • Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 57a3d89831fcaa2cdbe024b47c7c36d5a56c3637, af77c4fc1871847b528d58b7fdafb4aa1f6a9262, c031d286eceb82f72f8623b7f4abd2aa491bfb5e or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() xattr in ocfs2 maybe 'non-indexed', which saved with additional space requested. It's better to check if the memory is out of bound before memcmp, although this possibility mainly comes from crafted poisonous images.
