CVE-2024-53197: Linux Kernel Out-of-Bounds Access Vulnerability

CVE-2024-53197 · Severity: critical · CVSS 7.8 · Exploited in the wild · Published 2025-04-09

The Linux kernel USB-audio driver contains an out-of-bounds access vulnerability affecting Extigy and Mbox devices. A malicious USB device can provide a bNumConfigurations value that exceeds the expected allocation, leading to memory corruption during configuration destruction. This flaw can be exploited by an attacker with physical access to escalate privileges or execute arbitrary code.

Technologies: Linux Kernel. Vendors: Linux.
