CVE-2023-54079 remediation guide

Linux

In the Linux kernel, the following vulnerability has been resolved: power: supply: bq27xxx: Fix poll_interval handling and races on remove Before this patch bq27xxx_battery_teardown() was setting poll_interval = 0 to avoid bq27xxx_battery_update() requeuing the delayed_work item. There are 2 problems with this: 1. If the driver is unbound through sysfs, rather then the module being rmmod-ed, this changes poll_interval unexpectedly 2. This is racy, after it being set poll_interval could be changed before bq27xxx_battery_update() checks it through /sys/module/bq27xxx_battery/parameters/poll_i...

Identify the affected asset

Confirm whether Linux 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: >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < 4c9615474fb0a41cfad658d78db3c9ec70912969, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < 465d919151a1e8d40daf366b868914f59d073211, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < 0c5f4cec759679c290720fbcf6bb81768e21c95b, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < e85757da9091998276ff21a13915ac25229cc232, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < e98e5bebfcafc75a7b41192a607dfea5c1268afa, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < d952a1eaafcc5f0351caad5dbe9b5b3300d1d529, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < b12faeca0e819ea09051a705fef9df7ea7e9e18c, >= 8cfaaa811894a3ae2d7360a15a6cfccff3ebc7db < c00bc80462afc7963f449d7f21d896d2f629cacc, >= 3.3. 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: No verified fixed-version field is available yet. 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.
