Vulnerability from variot - Updated: 2025-01-30 21:09

The ThreadX-based firmware on Marvell Avastar Wi-Fi devices, models 88W8787, 88W8797, 88W8801, 88W8897, and 88W8997, allows remote attackers to execute arbitrary code or cause a denial of service (block pool overflow) via malformed Wi-Fi packets during identification of available Wi-Fi networks. Exploitation of the Wi-Fi device can lead to exploitation of the host application processor in some cases, but this depends on several factors including host OS hardening and the availability of DMA. plural Marvell Made Avastar wireless SoC The model includes Wi-Fi Multiple vulnerabilities exist including memory block pool overflow during network scans. ZeroNights 2018 Conference In Marvell Avastar SoC Several vulnerabilities were introduced and details about memory block pool overflow were announced. Wi-Fi An overflow condition occurs during a network scan, overwriting data in a specific memory block pool. Many devices automatically perform network scanning in the background, so this vulnerability can be exploited regardless of whether the target device is connected to a wireless network and without user intervention. There is a possibility.Wi-Fi Specially crafted by unauthenticated attackers within reach of Wi-Fi Using frames Marvell SoC Arbitrary code may be executed on systems with. Depending on the implementation method, it was attacked SoC Can be used to intercept network traffic and execute code on the host system. MarvellAvastar Wi-Fi is a WiFi chipset used in routers, computers and other devices. A security hole exists in the ThreadX-based firmware on MarvellAvastar Wi-Fi. Multiple Marvell SOCs are prone to arbitrary code-execution vulnerabilities. An attacker can leverage these issues to execute arbitrary code in the context of the affected system

Exploitation of the Wi-Fi device can lead to exploitation of the host application processor in some cases, but this depends on several factors including host OS hardening and the availability of DMA. plural Marvell Made Avastar wireless SoC The model includes Wi-Fi Multiple vulnerabilities exist including memory block pool overflow during network scans. ZeroNights 2018 Conference In Marvell Avastar SoC Several vulnerabilities were introduced and details about memory block pool overflow were announced. Wi-Fi An overflow condition occurs during a network scan, overwriting data in a specific memory block pool. Many devices automatically perform network scanning in the background, so this vulnerability can be exploited regardless of whether the target device is connected to a wireless network and without user intervention. There is a possibility.Wi-Fi Specially crafted by unauthenticated attackers within reach of Wi-Fi Using frames Marvell SoC Arbitrary code may be executed on systems with. Depending on the implementation method, it was attacked SoC Can be used to intercept network traffic and execute code on the host system. MarvellAvastar Wi-Fi is a WiFi chipset used in routers, computers and other devices. A security hole exists in the ThreadX-based firmware on MarvellAvastar Wi-Fi. Multiple Marvell SOCs are prone to arbitrary code-execution vulnerabilities. \nAn attacker can leverage these issues to execute arbitrary code in the context of the affected system",

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
