CVE-2026-1764
Description
A flaw was found in GNOME localsearch (previously known as tracker-miners) MP3 Extractor. When processing specially crafted MP3 files containing ID3v2.4 tags, a missing bounds check in the extract_performers_tags function can lead to a heap buffer overflow. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by triggering a read of unmapped memory. In some cases, it could also lead to information disclosure by reading visible heap data.
Statement
This vulnerability has MODERATE impact. A heap buffer overflow in tracker-extract-mp3 can occur when parsing specially crafted MP3 files containing ID3v2.4 tags. This flaw could lead to a denial of service or information disclosure if a user processes a malicious MP3 file within a desktop environment utilizing the localsearch component.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
