CVE-2022-49860: dmaengine: ti: k3-udma-glue: fix memory leak when register device fail

In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-glue: fix memory leak when register device fail If device_register() fails, it should call put_device() to give up reference, the name allocated in dev_set_name() can be freed in callback function kobject_cleanup().

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel memory-leak flaw in a TI K3 DMA driver error path. A local, low-privileged user may be able to trigger repeated failures that consume memory and affect availability. The sources do not show data theft, integrity impact, remote exploitation, or active exploitation.

Executive priority

Treat as a moderate availability risk, highest for embedded or appliance fleets using TI K3 platforms. It does not currently warrant emergency response based on the supplied evidence, but it should enter normal kernel patch cycles and local-user risk reviews.

Technical view

The issue is CWE-401 in dmaengine ti k3-udma-glue. If device_register() fails, the code must call put_device() so the dev_set_name() allocation can be freed through kobject cleanup. CVSS 3.1 is 5.5: local, low complexity, low privileges, no UI, availability high.

Likely exposure

Exposure is most relevant to Linux systems running affected kernel builds with the TI K3 UDMA glue driver present or enabled. General Linux servers without this driver or hardware path are less likely exposed, but distribution backports should be verified.

Exploitation context

The bundle marks KEV as false and cites no active exploitation. The CVSS vector requires local access and low privileges. Impact is availability only, likely through memory exhaustion if the vulnerable failure path can be repeatedly reached.

Researcher notes

Evidence is limited to the CVE record and Linux stable commit references. The simplified affected-version data is ambiguous, so rely on vendor kernel advisories and commit backport status for exact exposure. Do not assume exploitability beyond local availability impact.

Mitigation direction

  • Update to a kernel or vendor package containing the referenced stable fixes.
  • If no vendor package is available, monitor Linux and distribution advisories for backports.
  • Reduce exposure to untrusted local users on affected systems until patched.
  • Review whether the TI K3 UDMA glue driver is needed and enabled.

Validation and detection

  • Inventory kernel versions and distribution package patch levels across Linux assets.
  • Check whether the TI K3 UDMA glue driver is built, loaded, or required.
  • Map installed kernels against vendor advisories and the cited stable commits.
  • Confirm no affected appliance or embedded Linux image is outside update coverage.

Missing Release of Memory after Effective Lifetime

Missing Release of Memory after Effective Lifetime represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
