DescriptionCVE.org

A flaw was found in the tracker-extract-mp3 component of GNOME localsearch (previously known as tracker-miners). This vulnerability, a heap buffer overflow, occurs when processing specially crafted MP3 files. A remote attacker could exploit this by providing a malicious MP3 file, leading to a Denial of Service (DoS) where the application crashes. It may also potentially expose sensitive information from the system's memory.

AnalysisAI

Out-of-bounds read in the tracker-extract-mp3 component of GNOME localsearch (formerly tracker-miners) allows a low-privileged local user to trigger an application crash or leak sensitive process memory when the indexer parses a specially crafted MP3 file. Affected deployments include Red Hat Enterprise Linux 8, 9, and 10 running the GNOME desktop stack. No public exploit or active exploitation has been identified at time of analysis, though the file-based delivery mechanism - providing a malicious MP3 to a system where localsearch auto-indexes media - keeps realistic attacker reach higher than the AV:L vector alone implies.

Technical ContextAI

GNOME localsearch (upstream package previously known as tracker-miners) is a metadata extraction and indexing framework that automatically processes media files, including MP3 audio, dropped into monitored filesystem directories. The tracker-extract-mp3 sub-component parses ID3 tags and audio frame headers; a malformed MP3 can trigger an out-of-bounds read (CWE-125) on the heap, reading past a buffer boundary. Note: the CVE description uses the phrase 'heap buffer overflow,' but the assigned CWE-125 specifically denotes an out-of-bounds read rather than a write overrun (CWE-787/CWE-122). The confidentiality impact (C:L) is consistent with CWE-125 - heap contents adjacent to the buffer may be exposed. Affected CPEs span the GNOME subsystem as shipped in Red Hat Enterprise Linux 8, 9, and 10 (cpe:2.3:a:red_hat:red_hat_enterprise_linux_8/9/10).

RemediationAI

Patch available per vendor advisory - exact fixed package versions have not been independently confirmed from the available reference data; consult the Red Hat security advisory at https://access.redhat.com/security/cve/CVE-2026-1765 and the associated Bugzilla report at https://bugzilla.redhat.com/show_bug.cgi?id=2435981 for current package versions and errata. On RHEL systems, apply available errata via 'dnf update tracker-miners' once released. As a compensating control pending patching, administrators can disable the GNOME localsearch/tracker indexing service using 'systemctl --user mask tracker-extract-3.service tracker-miner-fs-3.service', which prevents automatic MP3 processing at the cost of disabling file metadata search within the GNOME desktop. This control has the side effect of breaking 'Files' application search and GNOME Tracker-dependent applications. Restricting untrusted media files from entering user home directories or monitored mount points via endpoint DLP or filesystem permissions is an additional compensating measure.
