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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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.

What to do

AI-suggested

1. Monitor Qualcomm and device vendor advisories closely for official patches or firmware updates addressing CVE-2025-47342 and apply them promptly upon release. 2. Where feasible, disable multi-profile concurrency and/or Qualcomm High-Speed (QHS) mode on affected devices to prevent triggering the use-after-free condition. 3. Limit network exposure of devices using vulnerable Snapdragon audio platforms by segmenting them on dedicated VLANs or restricting Bluetooth and network access to trusted sources only. 4. Implement strict access controls and privilege management to minimize the risk posed by the required low privileges for exploitation. 5. Conduct thorough testing of audio devices in controlled environments to detect any signs of transient DoS or instability related to this vulnerability. 6. Develop incident response plans that include procedures for handling audio service disruptions and potential device reboots or resets. 7. Engage with device manufacturers to understand the deployment of affected chipsets and request security status updates. 8. Educate end-users and IT staff about the symptoms of this vulnerability to enable early detection and reporting. 9. Consider alternative hardware or software solutions if mitigation options are limited and the risk is unacceptable.

Description

CVE-2025-47342 is a high-severity use-after-free vulnerability (CWE-416) affecting multiple Qualcomm Snapdragon audio platforms, including QCC5161, QCC7225, QCC7226, QCC7228, and various S3 and S5 Sound Platforms. The flaw arises when multi-profile concurrency is enabled with Qualcomm High-Speed (QHS) mode active, potentially causing a transient denial-of-service (DoS) condition. Exploitation requires network-level access with low privileges but no user interaction, and it can result in loss of availability due to improper memory handling. No known exploits are currently reported in the wild, and no patches have been published yet. European organizations using affected Snapdragon audio chipsets in their devices may experience service interruptions or degraded audio functionality. Mitigation involves closely monitoring vendor advisories for patches, limiting network exposure of affected devices, and disabling multi-profile concurrency or QHS mode where feasible. Countries with significant consumer electronics manufacturing and high adoption of Qualcomm Snapdragon-based devices, such as Germany, France, and the UK, are most likely to be impacted. Given the potential for denial-of-service and ease of exploitation, this vulnerability is rated as high severity and requires prompt attention from security teams managing affected hardware.

Impact

For European organizations, the primary impact of CVE-2025-47342 is the potential for transient denial-of-service conditions affecting audio functionality in devices using the vulnerable Qualcomm Snapdragon chipsets. This can disrupt communication, multimedia, and operational workflows dependent on these audio platforms. Industries such as telecommunications, consumer electronics manufacturing, and enterprises deploying Bluetooth audio devices may face service degradation or interruptions. The integrity impact, while lower, could affect audio data streams, potentially causing corrupted audio output. Although the vulnerability does not directly compromise confidentiality, the availability impact can lead to operational downtime or degraded user experience. Given the widespread use of Qualcomm Snapdragon chipsets in consumer and industrial devices across Europe, the vulnerability could affect a broad range of sectors, including automotive infotainment systems, healthcare devices, and smart home products. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once patches are released. Organizations relying on these devices should assess their exposure and prepare for incident response related to audio service disruptions.

Summary

CVE-2025-47342 is a use-after-free vulnerability categorized under CWE-416 found in Qualcomm Snapdragon audio platforms, specifically affecting chipsets QCC5161, QCC7225, QCC7226, QCC7228, and the S3 and S5 Sound Platforms. The vulnerability manifests when multi-profile concurrency is enabled alongside Qualcomm High-Speed (QHS) mode, which is a feature designed to optimize Bluetooth audio performance by allowing multiple audio profiles to operate concurrently. The use-after-free condition occurs due to improper memory management within the audio firmware or driver code, where a memory object is freed but subsequently accessed, leading to undefined behavior. This can cause a transient denial-of-service (DoS) condition, disrupting audio services temporarily. The CVSS v3.1 score of 7.1 reflects a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The impact primarily affects availability (A:H) and integrity (I:L), with no confidentiality impact (C:N). Although no exploits have been reported in the wild, the vulnerability poses a risk to devices using these chipsets, especially in environments where multi-profile concurrency and QHS are enabled. The lack of published patches necessitates proactive mitigation strategies. This vulnerability is particularly relevant for embedded systems and consumer electronics relying on Qualcomm Snapdragon audio platforms, including wireless earbuds, headsets, and smart speakers.

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
