CVE-2024-53150
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.
do firstUpgrade to a fixed release: < 5.4, >= 5.4.287 and <= 5.4.*, >= 5.10.231 and <= 5.10.*, >= 5.15.174 and <= 5.15.* (+5 more below).
Can a WAF block it? No. The attack needs local access to the machine, so a WAF is not on its path.

Based on the attack vector (local or physical access). We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.
Is CVE-2024-53150 being exploited?
Yes. CVE-2024-53150 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.
How severe is CVE-2024-53150?
CVE-2024-53150 is rated High with a CVSS score of 7.1. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2024-53150?
Yes. A fix has been recorded for CVE-2024-53150. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2024-53150 affect?
CVE-2024-53150 affects debian:debian_linux, linux:linux_kernel. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
