Summary
The dr_libs audio decoding library, specifically its dr_mp3 MP3 decoder, contains an out-of-bounds read flaw that a crafted .mp3 file can trigger. It can be reached remotely without logging in, but a user must open the malicious file for the attack to work, and it can expose limited data from memory.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-11315 (A out-of-bounds read vulnerability exists in the dr_mp3 drmp3_init_internal functionality of dr_libs (version(s): 0.7.3).), using the cve.now data below. Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only. What cve.now has for CVE-2026-11315 (entry last updated 2026-11-10): Affected: - mackron dr_libs: versions 0.7.3 Fixed versions: none listed yet. Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory. CISA KEV: CVE-2026-11315 is not listed as of cve.now's last read. This KEV status is for CVE-2026-11315 only. If you also check another CVE, look up its own KEV status; never assume it from this one. How to check: - Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory. Verify against the linked advisories before concluding, and cite the date you read each one: - https://talosintelligence.com/vulnerability_reports/TALOS-2026-2441 Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing. Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action. Entry: https://cve.now/CVE-2026-11315 For follow-up questions, use the cve.now MCP server at https://mcp.cve.now/mcp (no authentication), for example get_vulnerability with id CVE-2026-11315.
