CVE-2026-108822 Kamailio CVE debrief

Who should care

Defenders responsible for Kamailio deployments should assess exposure and prioritize upgrading to version 6.0.8 or 6.1.4. Affected operators, platforms, and security teams need to review vulnerability management and ensure system security. This includes verifying affected versions, configurations, and applying patches or mitigations as needed. Security teams should also monitor for potential remote attacks and review system logs for suspicious activity.

Why it matters

Defenders should prioritize upgrading to version 6.0.8 or 6.1.4 to address the buffer overflow vulnerability in Kamailio's sipt module, as remote attackers may exploit it.

• Remote attackers may exploit the buffer overflow vulnerability
• Successful exploitation could lead to system compromise
• Defenders should verify affected versions and upgrade to patched versions
• Exposure requires verification from official sources

Technical summary

The vulnerability is caused by a buffer overflow in the isup_get_calling_party function of the src/modules/sipt/ss7_parser.c file in the sipt Module of Kamailio up to 6.0.7/6.1.3. The attack may be performed from remote. Official sources confirm this vulnerability in affected versions. Defenders should assess exposure and prioritize upgrading to patched versions. Limited technical detail is available; defensive verification tasks are recommended. The buffer overflow occurs when the argument length is manipulated, potentially leading to system compromise.

Defensive priority

Defenders should prioritize upgrading to version 6.0.8 or 6.1.4 to address the buffer overflow vulnerability in Kamailio's sipt module.

Recommended defensive actions

• Upgrade to version 6.0.8 or 6.1.4
• Review and update affected versions
• Monitor for remote attacks
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
