CVE-2026-1766
MEDIUM 5.6A flaw was found in GNOME localsearch (previously known as tracker-miners) MP3 Extractor, specifically within the tracker-extract-mp3 component. This heap buffer overflow vulnerability occurs when processing specially crafted MP3 files containing malformed ID3v2.3 COMM (Comment) tags. An attacker could exploit this by providing a malicious MP3 file, leading to a denial of service (DoS), which causes an application crash, and potentially disclosing sensitive information from the heap memory.
No known exploitation, public exploit, or elevated probability at this time. Track for changes.
