CVE-2024-42284: tipc: Return non-zero value from tipc_udp_addr2str() on error

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: 0.92% (FIRST EPSS); higher than 60.5% 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 253405541be2f15ffebdeac2f4cf4b7e9144d12f, 2abe350db1aa599eeebc6892237d0bce0f1de62a, 5eea127675450583680c8170358bcba43227bd69; Azure Linux 3.0 ARM 6.6.47.1-1; Azure Linux 3.0 x64 6.6.47.1-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 253405541be2f15ffebdeac2f4cf4b7e9144d12f, 2abe350db1aa599eeebc6892237d0bce0f1de62a, 5eea127675450583680c8170358bcba43227bd69; Azure Linux 3.0 ARM 6.6.47.1-1; Azure Linux 3.0 x64 6.6.47.1-1 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: tipc: Return non-zero value from tipc_udp_addr2str() on error tipc_udp_addr2str() should return non-zero value if the UDP media address is invalid. Otherwise, a buffer overflow access can occur in tipc_media_addr_printf(). Fix this by returning 1 on an invalid UDP media address.
