CVE-2024-46736: smb: client: fix double put of @cfile in smb2_rename_path()

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.60% (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 1a46c7f6546b73cbf36f5a618a1a6bbb45391eb3, 3523a3df03c6f04f7ea9c2e7050102657e331a4f, 6.6.51.
  • Severity is disputed: the assigning authority (CNA) scores it 9.8, NVD 7.8.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1a46c7f6546b73cbf36f5a618a1a6bbb45391eb3, 3523a3df03c6f04f7ea9c2e7050102657e331a4f, 6.6.51 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix double put of @cfile in smb2_rename_path() If smb2_set_path_attr() is called with a valid @cfile and returned -EINVAL, we need to call cifs_get_writable_path() again as the reference of @cfile was already dropped by previous smb2_compound_op() call.
