In this article, we will be discussing a newly discovered vulnerability in the software component sdp_utils.cc. This vulnerability has been assigned the identifier CVE-2024-34727. We will discuss the details of this vulnerability, including the code snippet where the issue is present, the original references, and any available exploits. The vulnerability is a possible out-of-bounds read due to a heap buffer overflow, which can lead to remote information disclosure without additional execution privileges. Furthermore, user interaction is not required for exploitation.

Issue Details

CVE-2024-34727 exists in a function called sdpu_compare_uuid_with_attr in the source code file sdp_utils.cc. This vulnerability is a potential out-of-bounds read due to a heap buffer overflow. This means that an attacker could potentially read sensitive data by overflowing the buffer, leading to unauthorized access to system information. This could compromise the confidentiality and integrity of the affected system, which is a serious security concern. Moreover, the exploitation of this vulnerability requires no additional execution privileges and does not need any user interaction.

Code Snippet

The code snippet where the vulnerability exists in sdp_utils.cc is shown below:

int sdpu_compare_uuid_with_attr(UUID *p_uuid, tSDP_DISCOVERY_DB *p_db, tSDP_DISC_REC *p_rec) {
  UINT8 *p_attr_buff = (UINT8 *)(p_db->attr_seq.attr_entry[].start);

  for (uint16_t xx = ; xx < p_db->attr_seq.num_attr; xx++) {
    if (p_attr_buff[xx * 2 + 1] == (p_uuid->len - 1)) {
      if (!memcmp(p_attr_buff + xx * 2, p_uuid->uuid128, (size_t)(p_uuid->len))) {
        return 1;
      }
    }
  }

  return ;
}
