CISA KEV Advisory
Linux Kernel Out-of-Bounds Access Vulnerability
Linux Kernel contains an out-of-bounds access vulnerability in the USB-audio driver that allows an attacker with physical access to the system to use a malicious USB device to potentially manipulate system memory, escalate privileges, or execute arbitrary code.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This high-severity vulnerability in the Linux Kernel's USB-audio driver allows an attacker with physical access to use a malicious USB device to potentially manipulate system memory, escalate privileges, or execute arbitrary code. Its inclusion in CISA's KEV catalog and an EPSS score of 0.01584 indicate confirmed exploitation and a notable likelihood of future exploitation.
This vulnerability is actively being exploited in the wild, confirming its use by attackers. Exploitation requires physical access to the system via a malicious USB device.
Apply the latest security updates for the Linux Kernel. Restrict physical access to systems and implement strict controls over USB device usage.
Technical Analysis
CVE-2024-53197 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2024-53197 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
