CVE-2022-50198: ARM: OMAP2+: Fix refcount leak in omap3xxx_prm_late_init
In the Linux kernel, the following vulnerability has been resolved:
ARM: OMAP2+: Fix refcount leak in omap3xxx_prm_late_init
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
Security readout for executives and security teams
Plain-English summary
This CVE is a Linux kernel resource leak in ARM OMAP3 initialization code. The described impact is a missed reference release, not a direct remote compromise. Business urgency is mainly for embedded or legacy ARM devices running affected kernels, especially where uptime and resource stability matter.
Executive priority
Track this as low-priority maintenance unless your organization operates ARM OMAP embedded devices. For exposed products, fold remediation into the next kernel maintenance cycle unless vendor guidance raises severity.
Technical view
The issue is in omap3xxx_prm_late_init. of_find_matching_node() increments a device-tree node reference count, but the code did not call of_node_put() when finished. The kernel stable fixes add the missing release to avoid a refcount leak.
Likely exposure
Exposure appears limited to Linux systems using ARM OMAP2/OMAP3 platform code on affected kernel versions. Typical cloud, workstation, and x86 server fleets are unlikely to be exposed unless they build or ship this ARM platform support.
Exploitation context
The source bundle does not show public exploitation, KEV listing, exploit code, or attacker prerequisites. It documents a kernel refcount leak fixed in stable kernel commits, so exploitation claims should not be made from the available evidence.
Researcher notes
Evidence supports a reference-count leak in a narrow ARM platform initialization path. No CVSS, CWE, or exploit detail is provided. Treat impact analysis as constrained until vendor advisories or downstream distro notes clarify affected configurations.
Mitigation direction
Inventory Linux kernels used in ARM OMAP2/OMAP3 embedded devices.
Apply vendor-supported kernel updates containing the referenced stable fixes.
Check Linux distribution or device vendor advisories for backported patches.
Prioritize long-running devices where resource leaks can affect stability.
Validation and detection
Confirm whether deployed kernels include ARM OMAP2/OMAP3 support.
Compare kernel version and vendor patch level against supplied CVE records.
Review kernel changelogs for the referenced stable commit identifiers.
Verify updated builds include the missing of_node_put() fix.
