GNOME localsearch tracker-extract-mp3 Buffer Overflows

Heap buffer overflow in GNOME localsearch (formerly tracker-miners) tracker-extract-mp3 component on Red Hat Enterprise Linux 8/9/10, Ubuntu, Debian, and SUSE allows remote attackers to trigger an out-of-bounds heap read by delivering a malformed MP3 file with crafted ID3 performer tags, leading to crashes (DoS) or disclosure of process memory contents. No public exploit identified at time of analysis, and the EPSS score of 0.19% (9th percentile) plus CISA SSVC 'Exploitation: none' indicate low real-world exploitation activity despite the 8.1 CVSS rating. Vendor patches are available across Red Hat (RHSA), Ubuntu USN-8019-1, Debian, and SUSE-SU-2026:0780/21854.

Heap buffer overflow in GNOME localsearch's tracker-extract-mp3 component enables a local attacker to crash the metadata extraction daemon and potentially disclose heap memory contents by supplying a specially crafted MP3 file with malformed ID3v2.3 COMM tags. Affected platforms confirmed by Red Hat include RHEL 8, 9, and 10, where GNOME localsearch (formerly tracker-miners) runs as a background desktop search indexing service. No public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis; exploitation is further constrained by the requirement for local access, low privileges, and user interaction.

Heap out-of-bounds read in GNOME localsearch (formerly tracker-miners) MP3 Extractor affects Red Hat Enterprise Linux 8, 9, and 10, exploitable when a local user triggers indexing of a specially crafted MP3 file containing malformed ID3v2.4 tags. The missing bounds check in the `extract_performers_tags` function can cause a Denial of Service via an unmapped memory read, and in certain heap layout scenarios may also leak fragments of heap memory, resulting in limited information disclosure. No public exploit code has been identified at time of analysis and this vulnerability is not listed in the CISA KEV catalog.

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.
