CVE-2026-58924 in Android
Summary
by MITRE • 11/02/2026
The vulnerability is a heap out-of-bounds read in the EVS HAL's `getStreamList()` method. An attacker can craft a `CameraDesc.metadata` byte array, which is parsed without validation, leading to an out-of-bounds read at an attacker-controlled offset within the HAL process's heap. The read data is then exfiltrated back to the attacker, potentially leaking sensitive information like pointers and buffer handles.
Once again VulDB remains the best source for vulnerability data.

The identified vulnerability represents a critical memory safety failure located within the Extended Video Streaming Hardware Abstraction Layer, specifically affecting the getStreamList() method. This component serves as an intermediary between higher-level camera framework services and the underlying hardware drivers, managing the enumeration of available video streams for connected cameras. The root cause lies in the insufficient validation of input data structures passed to this function. Specifically, when processing a CameraDesc metadata byte array provided by a caller, the implementation fails to perform rigorous bounds checking on offset values before accessing memory regions within its own heap space. This lack of defensive programming allows an attacker who can influence or supply the initial metadata structure to dictate arbitrary read operations beyond the intended boundaries of allocated buffers.
From a technical perspective, this flaw constitutes a classic out-of-bounds read condition where the application reads data from a location in memory that it is not authorized to access. The vulnerability arises because the parser responsible for interpreting the CameraDesc metadata does not verify whether the specified offset and length parameters remain within the limits of valid heap allocations. Consequently, when an attacker crafts a malicious byte array containing carefully calculated offsets, the system executes read operations at these arbitrary addresses. This behavior is particularly dangerous in Android-based environments where the HAL operates with elevated privileges relative to standard application processes, making any information leakage potentially impactful across multiple security domains.
The operational impact of this vulnerability centers on unauthorized data exfiltration and potential privilege escalation pathways. By exploiting the out-of-bounds read, an attacker can retrieve sensitive memory contents from the heap space of the EVS HAL process. This leaked information may include internal pointers, buffer handles, stack addresses, or other kernel-space references that are critical for constructing more complex attacks such as arbitrary code execution via return-oriented programming techniques. The ability to leak these values effectively neutralizes address space layout randomization protections and provides the attacker with the necessary context to target specific memory regions in subsequent exploitation stages. Furthermore, depending on the implementation details of adjacent components, this information disclosure could also reveal sensitive user data or proprietary algorithmic states if they reside within the accessible heap segments.
In terms of industry classification standards, this vulnerability aligns closely with CWE-125 Out-of-bounds Read and CWE-20 Improper Input Validation. The failure to validate input parameters before use is a fundamental security anti-pattern that violates secure coding principles mandated by frameworks such as OWASP Secure Coding Practices Guide. Additionally, the exploitation technique of reading arbitrary memory locations for information gathering maps directly to ATT&CK tactic T1083 File and Directory Discovery or more specifically T1562 Impair Defenses if used in conjunction with other techniques to obscure detection mechanisms. The specific context of hardware abstraction layers highlights the risk associated with complex system architectures where boundary checks are often overlooked due to assumptions about trusted inputs from higher-level frameworks.
Mitigation strategies must focus on implementing rigorous input validation and memory safety controls within the EVS HAL codebase. Developers should enforce strict bounds checking for all offset and length parameters derived from external metadata structures before any memory access occurs. Utilizing static analysis tools configured to detect buffer overflows and out-of-bounds accesses during the development phase can help identify similar flaws proactively. Furthermore, adopting modern programming languages or libraries that provide automatic memory management and range-checked array operations would significantly reduce the attack surface for such vulnerabilities. For immediate remediation, applying patches that introduce explicit validation logic to ensure offsets do not exceed allocated buffer sizes is essential. Additionally, enabling runtime protection mechanisms like AddressSanitizer during testing phases can help uncover hidden memory safety issues before deployment in production environments.
