CVE-2022-50199: ARM: OMAP2+: Fix refcount leak in omapdss_init_of
In the Linux kernel, the following vulnerability has been resolved:
ARM: OMAP2+: Fix refcount leak in omapdss_init_of
omapdss_find_dss_of_node() calls of_find_compatible_node() to get device
node. of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() in later error path and normal path.
Security readout for executives and security teams
Plain-English summary
CVE-2022-50199 is a Linux kernel bug in ARM OMAP2+ display initialization. The kernel can keep an extra reference to a device-tree node instead of releasing it. The public sources do not provide CVSS, impact scope, or a named exploit outcome, so urgency should be based on affected asset presence.
Executive priority
Handle through normal kernel maintenance unless your environment includes critical ARM OMAP2+ embedded devices. There is not enough public evidence to justify emergency action, but affected systems should not be left untracked.
Technical view
The issue is a reference-count leak in omapdss_init_of. omapdss_find_dss_of_node calls of_find_compatible_node, which returns a node pointer with an incremented reference count. The fix adds missing of_node_put calls on later error and normal paths.
Likely exposure
Exposure appears limited to Linux kernels using the ARM OMAP2+ display subsystem code path. The source lists affected Linux versions and stable kernel commits, but does not identify specific distributions, appliances, or cloud services.
Exploitation context
The source bundle does not show CISA KEV listing, active exploitation, public exploit code, or attacker prerequisites. Treat exploitation likelihood as unconfirmed, not absent.
Researcher notes
The record describes a correctness fix for reference management, not a fully characterized security impact. No CWE, CVSS vector, exploitability details, or distribution-specific status are provided in the source bundle.
Mitigation direction
Update affected Linux kernels through vendor-supported packages or stable kernel releases.
Check whether vendor advisories map this CVE to your distribution or embedded kernel.
For maintained kernel trees, confirm the referenced stable commits are applied.
Prioritize business-critical ARM OMAP2+ embedded systems first.
Validation and detection
Inventory Linux assets using ARM OMAP2+ or related display subsystem code.
Compare running kernel versions and source trees against the affected versions and stable commits.
Review vendor kernel changelogs for CVE-2022-50199 or the referenced commit hashes.
Confirm omapdss_init_of releases the device-tree node on normal and error paths.
