# CVE-2026-89467

## Summary

- **CVE ID:** CVE-2026-89467
- **Severity:** UNKNOWN
- **CVSS Score:** 1.51
- **CWE:** N/A
- **Published:** Sep 11, 2026
- **Last Modified:** Sep 16, 2026

## Description

In the Linux kernel, the following vulnerability has been resolved:

power: supply: qcom_battmgr: fix use-after-free

qcom_battmgr_pdr_notify() queues enable_work when the PMIC GLINK service
comes up, and the worker recovers battmgr through container_of() to issue
firmware requests. The PMIC GLINK client stays on the client list until
its devres release action runs, so a PDR notification can keep queueing
the work, and a pending or running worker can access battmgr after devres
frees it.

Make enable_work device-managed with devm_work_autocancel(), registered
before the PMIC GLINK client is allocated. The devres cleanup then
releases the client first, so no further notification can queue the work,
and cancels the work before battmgr is freed.

This issue was found by an in-house static analysis tool.
