🟢 CVE-2024-53150

CVE-2024-53150 is a vulnerability identified in the Linux kernel's USB Audio driver, specifically involving an out-of-bounds read issue when the driver traverses clock descriptors ^{[3] [1]}.

Below is the requested information regarding this vulnerability:

Exploitation and Threat Actor Usage

• Active Exploitation: There is no evidence of active exploitation in the wild or usage by specific threat actors. It is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog.
• Ransomware/Targeted Attacks: There are no reports linking this vulnerability to ransomware campaigns or targeted attacks.

Attack Method and Requirements

• Exploitation Requirements: Successful exploitation typically requires physical access to the system ^[1].
• Method: An attacker would need to connect a malicious USB device to the target system to trigger the flaw in the USB Audio driver's descriptor parsing logic ^[1].
• User Interaction: Generally, no specific user interaction is required beyond the physical insertion of the malicious device.

Impact and Access

• Impact: The vulnerability allows for out-of-bounds reads. In the context of kernel drivers, such flaws can potentially lead to information disclosure or system instability (e.g., kernel crashes/denial of service), depending on the specific memory layout and the nature of the data accessed.

Proof-of-Concept and Availability

• There are no widely publicized, functional exploit tools or proof-of-concept (PoC) exploits available for this vulnerability.

Affected Versions and Mitigation

• Affected Versions: The vulnerability affects various versions of the Linux kernel where the USB Audio driver fails to properly validate the `bLength` of descriptors during traversal.
• Patch Status: This issue was resolved in the Linux kernel source tree. Users and administrators should ensure their systems are updated to a kernel version that includes the fix (typically found in stable kernel releases distributed by major Linux distributions) ^{[2] [4]}.
• Mitigation: The primary mitigation is to apply the relevant security updates provided by your Linux distribution vendor. As the attack requires physical access, maintaining physical security of hardware is a standard defensive practice.
