Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 10 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Users of dr_libs version 0.7.3 should monitor vendor advisories for updates or patches addressing this issue. Until a fix is available, avoid processing untrusted or malicious .mp3 files with the affected version to reduce risk.

Description

CVE-2026-11315 is an out-of-bounds read vulnerability in the dr_mp3 drmp3_init_internal function of dr_libs version 0.7.3. This flaw can be triggered by processing a specially crafted .mp3 file, potentially causing memory to be read beyond its intended bounds. The vulnerability has a medium severity rating with a CVSS score of 4.3.

Impact

Successful exploitation of this vulnerability could allow an attacker to cause an out-of-bounds read, potentially leading to information disclosure or application instability. However, the impact is limited to confidentiality loss only, with no integrity or availability impact reported. There are no known exploits in the wild at this time.

Summary

This vulnerability involves an out-of-bounds read in the dr_mp3 drmp3_init_internal functionality of the dr_libs library, specifically in version 0.7.3. An attacker can exploit this by supplying a maliciously crafted .mp3 file that triggers the out-of-bounds read condition. The flaw is categorized under CWE-125 (Out-of-bounds Read). No public exploits or known active exploitation have been reported. The CVSS 3.1 base score is 4.3, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, user interaction required, and limited confidentiality impact.

Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.

Use a language that provides appropriate memory abstractions.
