CVE-2026-43295 Details
Description
In the Linux kernel, the following vulnerability has been resolved: rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net() When idtab allocation fails, net is not registered with rio_add_net() yet, so kfree(net) is sufficient to release the memory. Set mport->net to NULL to avoid dangling pointer.
A vulnerability in the Linux kernel's RapidIO driver has been addressed. The issue involved improper memory management in the net allocation process for RapidIO ports. When the destination ID table allocation failed, the allocated net structure was not yet registered with the network management functions, leading to a potential memory leak. The fix involved changing the memory deallocation function to properly release the allocated resources and prevent dangling pointers.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed.
