CVE-2026-24089 Memory Corruption Vulnerability in Fastboot Command Processing

CVE-2026-24089 is a memory corruption vulnerability affecting devices that process fastboot commands. The vulnerability stems from improper handling of invalid input during fastboot command processing. While the specific vulnerable products are not detailed in the source document, exploitation requires physical access to the device, limiting the scope of potential attacks. This vulnerability was reported by Qualcomm, Inc., and is detailed in their June 2026 security bulletin. Exploitation could lead to device compromise.

Attack Chain

1. Attacker gains physical access to a vulnerable device.
2. Attacker initiates fastboot mode on the device.
3. Attacker sends crafted fastboot commands with invalid input.
4. The fastboot processing module fails to properly validate the input.
5. A memory corruption occurs due to the invalid input.
6. The corrupted memory region is accessed, leading to unexpected behavior.
7. The attacker leverages the memory corruption to potentially execute arbitrary code.
8. The attacker gains control of the device or causes a denial-of-service condition.

Impact

Successful exploitation of CVE-2026-24089 can lead to arbitrary code execution or a denial-of-service condition on the affected device. The need for physical access limits the number of potential victims, however, successful exploitation allows an attacker to gain significant control over the compromised device. The affected sectors are devices utilizing Qualcomm chipsets.

Recommendation

• Monitor process creation events for any unexpected or unusual processes spawned during fastboot mode (see generic process creation rules).
• Review and apply the security updates provided by Qualcomm in their June 2026 security bulletin to patch CVE-2026-24089.
• Implement robust input validation mechanisms to prevent the processing of malformed or invalid fastboot commands.
