CVE-2022-49163 remediation guide

Linux Linux, linux kernel

In the Linux kernel, the following vulnerability has been resolved: media: imx-jpeg: fix a bug of accessing array out of bounds When error occurs in parsing jpeg, the slot isn't acquired yet, it may be the default value MXC_MAX_SLOTS. If the driver access the slot using the incorrect slot number, it will access array out of bounds. The result is the driver will change num_domains, which follows slot_data in struct mxc_jpeg_dev. Then the driver won't detach the pm domain at rmmod, which will lead to kernel panic when trying to insmod again.

Identify the affected asset

Confirm whether Linux Linux, 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: >= 2db16c6ed72ce644d5639b3ed15e5817442db4ba < 02f9f97d54ffc85b50ad77f5b1f3c8f69cd17747, >= 2db16c6ed72ce644d5639b3ed15e5817442db4ba < 20c8b90430c5d6c4a3936eaa7c35aac670581487, >= 2db16c6ed72ce644d5639b3ed15e5817442db4ba < e209e6db2e527db6a93b14c2deedf969caca78fc, >= 2db16c6ed72ce644d5639b3ed15e5817442db4ba < 97558d170a1236280407e8d29a7d095d2c2ed554, >= 5.13, >= 5.13 < 5.15.33, >= 5.16 < 5.16.19, >= 5.17 < 5.17.2. Treat incomplete inventory results as unresolved.

Prioritize with independent signals

The CVSS severity warrants an early asset and exposure review. Combine this signal with asset criticality, exposure, compensating controls, and business impact.

Apply supported remediation

Follow the vendor advisory or supported update path. Current fixed-version status: 5.15.33, 5.16.19, 5.17.2. Preserve configuration and rollback material before change.

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.

Operational boundary

This page does not replace the vendor advisory, support contract, change-management process, or recovery plan. Do not infer that an asset is unaffected from an incomplete inventory query or a missing fixed-version field.
