CVE-2024-53150Known exploitationPublic exploit

Kernel memory disclosure via short clock descriptors

Published Dec 24, 2024 · Updated May 23, 2026

Out-of-bounds read in the Linux ALSA USB-audio driver allows physically proximate attackers to disclose kernel memory via a malicious USB device. The clock-descriptor validators in sound/usb/clock.c traverse descriptors without first checking bLength, so short source, multiplier, or selector descriptors make the driver read beyond their bounds and can return adjacent data in a USB control message. Exploitation requires physical USB attachment and controlled descriptor data; demonstrated attacks use heap grooming to leak a kernel pointer and bypass KASLR.
