Known exploited vulnerability
CVE-2024-53150
The short answer
CVE-2024-53150 affects Linux Linux and is rated high (CVSS 7.1). CISA added it to the Known Exploited Vulnerabilities catalog on 2025-04-09: attackers are using it, so patch it first. The vendor has linked a patch.
What it is
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix 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. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.
Weakness: CWE-125.
