CVE-2026-24088 — Missing Authentication for Critical Function in Boot

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

CISA SSVC assessment CISA

Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

• Documented patch — docs.qualcomm.com (NIST National Vulnerability Database)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

1. Identify exposed assets running the affected vendor/product/version combinations (Qualcomm Ar9380 Firmware, Qualcomm Csr8811 Firmware, Qualcomm Fastconnect 6200 Firmware…).
2. Apply the fixed version or the patch documented under Remediation.
3. Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

• Local/physical vector: focus on endpoint telemetry (EDR) from affected hosts.
• Review authentication logs: logins without MFA, anomalous sessions and recently created accounts.

What should defenders know first?

CVE-2026-24088 is "Missing Authentication for Critical Function in Boot", rated High. It affects Ar9380 Firmware (Qualcomm); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.2 describes technical severity. EPSS 0.07% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
