CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:HSummary
CVE-2026-1766 is a medium-severity Buffer Access with Incorrect Length Value (CWE-805) vulnerability in Redhat Enterprise Linux. Its CVSS base score is 5.6 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Malicious File (T1204.002); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-16 (Memory Protection) — see the control section below for these in your framework.

Vulnerability Data
A 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…
more
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.

Why these techniques?
Heap overflow in MP3 parser directly enables exploitation via a malicious file opened by the user.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of MP3 file input (ID3v2.3 COMM tags) to reject malformed lengths before buffer operations occur.
Enforces memory protections that block exploitation of the heap buffer overflow during tracker-extract-mp3 processing.
Requires integrity verification of files and executables to detect or block specially crafted MP3s before extraction.

Security testing in development can detect out-of-bounds accesses, but does not guarantee prevention.
Secure development life cycle mandates buffer-safety practices that directly prevent incorrect length values.
Application security requirements can specify buffer-size validation, but do not prescribe implementation details.
Secure architecture principles encourage bounds-checked APIs, yet leave concrete coding decisions to developers.
Secure coding explicitly requires correct buffer-length handling, eliminating CWE-805 when followed.
