CVE-2026-51272
AI Analysis
Technical Summary
In schreibfaul1 ESP32-audioI2S 3.4.5, the latinToUTF8() function performs character encoding conversion from Latin-1 to UTF-8. It calculates the required buffer size by doubling the input length and reallocates the heap buffer accordingly but lacks strict boundary checks. This can lead to insufficient buffer allocation when processing maliciously oversized input, causing a heap-based buffer overflow. The overflow may enable attackers to execute arbitrary code, disclose sensitive information, cause denial of service, or escalate privileges.
Potential Impact
The vulnerability allows an attacker to trigger a heap-based buffer overflow via crafted input to the latinToUTF8() function. This can lead to arbitrary code execution, information disclosure, denial of service, or privilege escalation within the affected application.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is available at this time.
