Description
A vulnerability was determined in Kamailio up to 5.5.0/6.0.7. This affects the function get_4bytes of the file src/modules/ims_registrar_scscf/cxdx_avp.c of the component AVP Handler. Executing a manipulation can lead to out-of-bounds read. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized. This patch is called abb5d60af6eefbd367bf6588c5589566b090e272. It is advisable to implement a patch to correct this issue. The vendor points out, that "[v]ersion 5.5.0 is old and not maintained anymore."
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-82608 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-82608 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-82608. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
