CVE-2026-87118
CVE-2026-87118 — Botslab G980H Dashcams Out-of-bounds Write
The Botslab G980H dash camera firmware contains an out of bounds write vulnerability in its command processing functionality. An authenticated attacker with adjacent network access could submit crafted command data that corrupts memory, potentially disrupting authentication state or causing the affected process to terminate and the device to restart, resulting in a temporary denial of service.

Remediation
The vendor's own words where we have them.
Upgrade G980H to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.
First 24 hours
Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.
- Identify exposed assets running affected vendor/product/version combinations.
- Prioritize based on EPSS, PoC availability, and external exposure.
- Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

Answered from this record1
What should defenders know first?
CVE-2026-87118 is Botslab G980H Dashcams Out-of-bounds Write, a medium vulnerability affecting G980H from Botslab. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-87118. Public exploit evidence is: 1 public PoC repositories reported; 0 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 5.7 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
