In the Linux kernel, the following vulnerability has been resolved: usb: musb: omap2430: Fix use-after-free in omap2430_probe() In omap2430_probe(),… (CVE-2026-63906)
A use-after-free vulnerability was identified and resolved in the Linux kernel's usb: musb: omap2430 driver. The issue occurred because of premature calls to of_node_put(np) before the last access to the node pointer np in the omap2430_probe() function. This could lead to a use-after-free condition if the node's reference count dropped to zero. The fix involved moving the of_node_put() calls to after the last use of np in both success and error paths.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel affects the usb: musb: omap2430 driver, specifically in the omap2430_probe() function. The premature release of a device tree node reference (of_node_put(np)) before the last access to np can cause a use-after-free condition if the reference count reaches zero. This flaw was corrected by adjusting the code to delay the release of the node reference until after its final use, preventing the use-after-free scenario.
Potential Impact
The use-after-free vulnerability could potentially lead to memory corruption within the kernel, which might be exploited to cause system instability or escalate privileges. However, no known exploits in the wild have been reported for this vulnerability. The impact is limited to systems running the affected Linux kernel driver for the omap2430 USB controller.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel by correcting the order of of_node_put() calls in the omap2430_probe() function. Users and administrators should apply the official kernel updates or patches that include this fix. Since this is a kernel-level issue, updating to a patched kernel version is the recommended remediation. Patch status is not explicitly confirmed in the provided data; therefore, check the official Linux kernel advisories or vendor updates for the exact patched versions and remediation guidance.
