Out-of-Bounds Read in Gnome (CVE-2026-1764)
Summary
Vulnerability in Gnome (CVE-2026-1764). Risk of unauthorized operations or information disclosure. Exploitable via extract_performers_tags.
Original description
The description as published by the source.
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.
