Siemens SCALANCE and RUGGEDCOM Devices Out-of-bounds Read (CVE-2024-53150)

high Tenable OT Security Plugin ID 504727

Synopsis

The remote OT asset is affected by a vulnerability.

Description

ALSA: usb-audio: out of bounds reads when finding clock sources The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of- bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop.
For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type.

This plugin only works with Tenable.ot.
