Integrity: None
Availability: None

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

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
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: 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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Aug 2026
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 2 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.

Until a patch is available, limiting exposure to untrusted adjacent networks may reduce risk.

Description

CVE-2026-24077 is an integer underflow vulnerability (CWE-191) in Qualcomm Snapdragon products that can lead to information disclosure when processing wireless network channel switch information with improperly formatted length fields. The vulnerability has a CVSS score of 6.5, indicating a medium severity. It affects a wide range of Qualcomm Snapdragon chipsets and related components. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.

Impact

Successful exploitation of this vulnerability can lead to disclosure of sensitive information due to improper processing of wireless network channel switch data. The impact is limited to confidentiality loss; integrity and availability are not affected. The attack requires adjacent network access, making remote exploitation more challenging but possible within a local network environment.

Summary

This vulnerability involves an integer underflow (wrap or wraparound) condition in Qualcomm Snapdragon products when processing wireless network channel switch information that contains improperly formatted length fields. The flaw can cause information disclosure due to incorrect handling of these length fields. The CVSS 3.1 vector indicates the attack requires adjacent network access (AV:A), has low attack complexity (AC:L), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality (C:H) without affecting integrity or availability. The affected products include a broad list of Qualcomm chipsets and wireless components, but no specific software versions or firmware releases are detailed.
