CVE-2024-47695: RDMA/rtrs-clt: Reset cid to con_num - 1 to stay in bounds

HighCVSS 7.8 · v3.1—No exploit Fix available

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: 0.68% (FIRST EPSS); higher than 53% of all records.
  • 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 01b9be936ee8839ab9f83a7e84ee02ac6c8303c4, 0429a4e972082e3a2351da414b1c017daaf8aed2, 1c50e0265fa332c94a4a182e4efa0fc70d8fad94; azl3 kernel 6.6.51.1-5 on Azure Linux 3.0 6.6.56.1-5; azl3 kernel 6.6.56.1-5 on Azure Linux 3.0 6.6.56.1-5.
  • Severity is disputed: the assigning authority (CNA) scores it 9.8, NVD 7.8.

Low priority for now. Upgrade to Linux Linux 01b9be936ee8839ab9f83a7e84ee02ac6c8303c4, 0429a4e972082e3a2351da414b1c017daaf8aed2, 1c50e0265fa332c94a4a182e4efa0fc70d8fad94; azl3 kernel 6.6.51.1-5 on Azure Linux 3.0 6.6.56.1-5; azl3 kernel 6.6.56.1-5 on Azure Linux 3.0 6.6.56.1-5 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-clt: Reset cid to con_num - 1 to stay in bounds In the function init_conns(), after the create_con() and create_cm() for loop if something fails. In the cleanup for loop after the destroy tag, we access out of bound memory because cid is set to clt_path->s.con_num. This commits resets the cid to clt_path->s.con_num - 1, to stay in bounds in the cleanup loop later.
