CVE-2023-53744: soc: ti: pm33xx: Fix refcount leak in am33xx_pm_probe

In the Linux kernel, the following vulnerability has been resolved: soc: ti: pm33xx: Fix refcount leak in am33xx_pm_probe wkup_m3_ipc_get() takes refcount, which should be freed by wkup_m3_ipc_put(). Add missing refcount release in the error paths.

Security readout for executives and security teams

Plain-English summary

This CVE is a Linux kernel bug in a Texas Instruments power-management driver. On certain error paths, the driver takes a reference and fails to release it. The sources do not provide CVSS, active exploitation evidence, or a quantified business impact.

Executive priority

Treat as a low-priority kernel maintenance item unless your environment includes TI AM33xx-based embedded devices. There is no sourced evidence of active exploitation or broad remote risk in the provided material.

Technical view

The resolved issue is a missing wkup_m3_ipc_put() after wkup_m3_ipc_get() in am33xx_pm_probe error paths under soc: ti: pm33xx. This is a refcount leak in Linux kernel driver initialization logic, addressed by referenced stable kernel commits.

Likely exposure

Exposure appears most relevant to Linux systems using TI AM33xx/pm33xx platform support. General-purpose servers without this driver or hardware path are less likely to be meaningfully exposed, but kernel package status should still be validated.

Exploitation context

The source bundle marks KEV as false and provides no cited evidence of active exploitation. It also does not describe an exploit technique, attacker prerequisites, or proven security impact beyond the refcount leak.

Researcher notes

Evidence is limited to the CVE record and upstream stable commits. No CVSS, CWE, exploit status, or detailed impact analysis is provided. Avoid assuming privilege escalation or remote attackability without additional vendor evidence.

Mitigation direction

  • Update affected Linux kernels to builds containing the referenced stable commits.
  • Check Linux distribution advisories for backported fixes.
  • Prioritize embedded or appliance systems using TI AM33xx/pm33xx platforms.
  • Track vendor kernel guidance where upstream commit mapping is unclear.

Validation and detection

  • Inventory kernel versions against the affected version list in the CVE bundle.
  • Identify systems using TI AM33xx/pm33xx platform support.
  • Review kernel changelogs or SBOMs for the referenced stable commit IDs.
  • Confirm patched code releases the wkup_m3_ipc reference on probe error paths.
