CVE-2026-51244 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 7.5 High
schreibfaul1 ESP32-audioI2S 3.4.5 has a buffer overflow vulnerability in UnpackFrameHeader(). Multiple attacker-controlled index parameters are used to access static and heap table arrays without range limitation. Invalid index values lead to out-of-bounds memory writing and heap buffer overflow.
CVE-2026-51251 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 7.5 High
Schreibfaul1 ESP32-audioI2S 3.4.5 has a buffer overflow vulnerability in the MP3Decoder::decode() function of the MP3 decoder due to missing size validation on untrusted mainDataBegin and nSlots values.
CVE-2026-51252 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 9.8 Critical
schreibfaul1 ESP32-audioI2S 3.4.5 has a buffer overflow vulnerability in the MP3Decoder::UnpackSFMPEG1 function due to missing input validation on attacker-controlled MP3 metadata.
CVE-2026-51261 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 9.8 Critical
Missing mutex synchronization in AudioBuffer::freeSpace() in schreibfaul1 ESP32-audioI2S 3.4.5 creates a race condition between concurrent tasks. The function calculates available buffer space without protecting shared read/write pointers, returning an incorrectly large value. Trusting this value leads to heap out-of-bounds write, memory corruption, device crash, and arbitrary code execution.
CVE-2026-51266 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 9.8 Critical
schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the HTTP request header construction logic. The application dynamically splices attacker-controlled host name, path, query string, and multiple HTTP header fields into a fixed ps_ptr heap buffer without proper size limitation and boundary validation. Remote attackers can use an oversized crafted network request parameter to trigger out-of-bounds heap write, leading to arbitrary code execution.
CVE-2026-51268 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 9.8 Critical
schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the host parsing logic. The dismantle_host() function parses untrusted host and URL input, and subsequent code uses clone_from() to copy parsed host, request host, extension and query_string segments into fixed heap buffers without boundary checking.
CVE-2026-51271 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 9.6 Critical
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the WAV header parsing function read_WAV_Header(). The function reads untrusted chunk size and bytes-to-skip value directly from malicious WAV files without reasonable range restriction. Abnormally large bts and headerSize values lead to out-of-bounds heap memory read/write during header parsing, which can be exploited to execute arbitrary code, disclose sensitive information, cause denial of service or escalate privileges.
CVE-2026-51273 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 7.8 High
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the ID3 tag parsing function showID3Tag() of the embedded audio streaming library. The program reads untrusted long ID3 tag value from malicious audio files and uses unbounded appendf() to write formatted strings into ps_ptr heap buffer without length validation. Successful exploitation allows attackers to execute arbitrary code, leak sensitive memory data, cause device crash, or escalate privileges via a crafted malicious audio file.
CVE-2026-51274 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 8.8 High
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 SYLT synchronized lyrics parser in audiolib allows remote attackers to cause a denial of service (application crash), information disclosure, or potential arbitrary code execution via a crafted MP3 file. The vulnerability occurs due to missing bounds validation on attacker-controlled frame size and improper memory access during lyric parsing.
CVE-2026-51275 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 8.8 High
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 APIC frame parsing function in audiolib allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a crafted MP3 file. The vulnerability exists due to missing length validation when processing the APIC frame size field, leading to an out-of-bounds memory write.
CVE-2026-51272 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 9.8 Critical
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the latinToUTF8() character encoding conversion function. The function calculates required buffer size by simply doubling input length and reallocates ps_ptr heap buffer without strict boundary validation. Malicious oversized input can trigger insufficient buffer allocation and out-of-bounds write during Latin-1 to UTF-8 conversion, leading to code execution, information disclosure, denial of service or privilege escalation.
CVE-2026-51270 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-30 8.8 High
schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the htmlToUTF8() HTML entity decoding function. The function parses attacker-controlled malicious HTML entities and uses memmove and memcpy to rearrange string content without validating buffer remaining size and boundary limits. Crafted oversized HTML entity strings can trigger heap out-of-bounds write, allowing remote code execution, memory information leakage, service crash or privilege escalation.
CVE-2026-51254 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-28 N/A
schreibfaul1 ESP32-audioI2S v3.4.5 has an integer underflow vulnerability in the MP3Decoder::GetBits() function of the MP3 decoder due to unchecked bit reading operations. The lack of validation on the nBits parameter causes the cachedBits counter to underflow to negative values, leading to invalid bit manipulation, incorrect bitstream parsing, application crash, or arbitrary code execution via a specially crafted MP3 file.
CVE-2026-51259 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-28 9.8 Critical
Unchecked unsigned integer overflow in buffer size calculation in schreibfaul1 ESP32-audioI2S 3.4.5 leads to undersized PSRAM buffer allocation. Subsequent normal audio buffer read and write operations cause heap out-of-bounds access, memory corruption, denial of service, and potential code execution.
CVE-2026-51260 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-28 9.4 Critical
Unsafe fixed-size memcpy operation in AudioBuffer::writeSpace() of schreibfaul1 ESP32-audioI2S 3.4.5 allows remote heap buffer overflow. The code copies a full UINT16_MAX bytes without validating destination available space, causing out-of-bounds memory write.
CVE-2026-51263 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-28 9.8 Critical
schreibfaul1 ESP32-audioI2S 3.4.5 is vulnerable to Buffer Overflow. The Audio::openai_speech function in the Audio library manually constructs JSON request bodies and HTTP request headers by directly concatenating externally controllable input and instructions strings without effective length restriction and boundary validation. An unauthenticated remote attacker can send oversized malicious string data to trigger a heap buffer overflow during string splicing, resulting in memory corruption.
CVE-2026-51267 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-28 9.8 Critical
schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the URL path concatenation and encoding module. The application splices untrusted extension path and attacker-controlled query string into a path buffer, then invokes urlencode without validating the final string length. Remote attackers can construct an oversized malicious URL path and query string to trigger out-of-bounds heap write, resulting in arbitrary code execution, information disclosure, service crash, or privilege escalation.
CVE-2026-51269 1 Schreibfaul1 1 Esp32-audioi2s 2026-07-28 8.8 High
schreibfaul1 ESP32-audioI2S 3.4.5 has a heap-based buffer overflow vulnerability in the connecttospeech() function. The application accepts attacker-controlled long speech text input, performs URL encoding, and directly appends the encoded result into a fixed ps_ptr heap buffer when constructing HTTP TTS request headers. Lack of input length validation and boundary checking allows remote attackers to craft oversized input to trigger out-of-bounds heap write, resulting in arbitrary code execution.
