Analysis Summary
# Vulnerability: Actively Exploited Privilege Escalation in Android Kernel (UVC Driver)
## CVE Details
- CVE ID: CVE-2024-53104
- CVSS Score: 7.8 (High - Implied based on successful exploitation leading to privilege escalation)
- CWE: Not explicitly specified, but relates to memory corruption vulnerabilities (Out-of-bounds write).
## Affected Systems
- Products: Android Operating System (Affected by kernel component patch).
- Versions: Unspecified, but patched in the February 2025 Android Security Bulletin.
- Configurations: Vulnerability exists in the USB Video Class (UVC) driver component, originating from the Linux kernel version 2.6.26 introduced change.
## Vulnerability Description
CVE-2024-53104 is a privilege escalation vulnerability residing in the Android kernel's USB Video Class (UVC) driver component. The flaw is identified as an **out-of-bounds write condition** occurring during the parsing of frames of type `UVC_VS_UNDEFINED` within the `uvc_parse_format()` function in the `uvc_driver.c` file. Successful exploitation could lead to memory corruption, program crash, or arbitrary code execution, resulting in privilege escalation.
## Exploitation
- Status: **Actively exploited in the wild** ("limited, targeted exploitation").
- Complexity: Implied Low/Medium, given targeted exploitation in the wild.
- Attack Vector: Likely Local or Adjacent, as interaction with USB hardware (UVC devices) is typically required, though the exact path is not detailed beyond "privilege escalation."
## Impact
- Confidentiality: Potential for high impact if local code execution is achieved.
- Integrity: Potential for high impact due to memory corruption/arbitrary code execution.
- Availability: Potential for system crash or instability.
## Remediation
### Patches
Google released patches as part of the February 2025 Android Security Bulletin, available in two patch levels:
- **2025-02-01**
- **2025-02-05** (Encouraged level)
### Workarounds
No specific workarounds were mentioned in the provided context, other than applying the official patches quickly. Given the nature of the flaw (UVC driver), temporarily disabling external USB cameras might be considered a temporary risk reduction measure, although this is not officially advised.
## Detection
- Indicators of Compromise (IoCs): The article does not list specific IoCs.
- Detection methods and tools: Monitoring memory corruption events or unauthorized privilege escalation attempts related to kernel operations involving USB video drivers may be relevant. Patching to the 2025-02-05 or later security level resolves the issue.
