CVE-2024-53150 remediation guide
Linux Kernel
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...
Identify the affected asset
Confirm whether Linux Kernel is installed, record the deployed version and installation path, and identify exposed interfaces.
- Record the product name, package or appliance identifier, and installed version.
- Identify internet-facing, administrative, API, and internal access paths.
- Preserve the pre-change configuration and relevant service logs.
Validate the affected-version match
Compare the deployed version with the affected range: b8e4f1fdfa422398c2d6c47bfb7d1feb3046d70a, 9feeaa50e5b4b0b71259d918a36ecf9059e60796, 3b17a13b687ae99939dc94a4ae01fbc34f68decc, 4.19.84, 5.3.11, 5.4, 11.0, < 5.4.287, >= 5.5 < 5.10.231, >= 5.11 < 5.15.174, >= 5.16 < 6.1.120, >= 6.2 < 6.6.64, >= 6.7 < 6.11.11, >= 6.12 < 6.12.2. Treat incomplete inventory results as unresolved.
Prioritize with independent signals
CISA has listed this vulnerability in the Known Exploited Vulnerabilities catalog. Combine this signal with asset criticality, exposure, compensating controls, and business impact.
Apply supported remediation
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Verify the result
Confirm the resulting version, service health, authentication and access paths, monitoring coverage, and relevant security logs.
- Confirm the expected version and package state.
- Run a functional health check for critical service paths.
- Review authentication, error, application, and security monitoring logs.
- Reassess exposure if the supported fix cannot be applied.
